+                    Adding more hooks is a simple matter of adding more

+
+        <para>
+            initramfs is the successor of Initial RAM Disk (initrd).
+            It is a "copy in and out" (cpio) archive of the initial file system
+            that gets loaded into memory during the Linux startup process.
+            Because Linux uses the contents of the archive during
+            initialization, the initramfs needs to contain all of the device
+            drivers and tools needed to mount the final root filesystem.
+        </para>
+
+        <para>
+            To build an initramfs image and bundle it into the kernel, set the

+            Setting the <filename>INITRAMFS_IMAGE_BUNDLE</filename>
+            flag causes the initramfs created by the recipe and defined by
+            <filename>INITRAMFS_IMAGE</filename> to be unpacked into the
+            <filename>${B}/usr/</filename> directory.
+            The unpacked initramfs is then passed to the kernel's

+            normally.
+            <note>
+                The preferred method is to use the
+                <filename>INITRAMFS_IMAGE</filename> variable rather than the

+Subject: [PATCH] stats: Fix bad file descriptor initialisation
+
+Stats file code initialises its file descriptor field to 0.  But 0 is
+a valid fd value. -1 should be used instead.  This causes problems
+when an error happens before a stats file is open (e.g. mkdir
+fails). The clean-up procedure, stats_free() calls close(fd).  When fd
+is 0, this first closes stdin, and then any files/sockets which
+received fd=0, re-used by the OS.
+
+Fixed several instances of bad file descriptor field handling, in case
+of errors.
+
+The bug results with connman freezing if there is no read/write storage
+directory available, and there are multiple active interfaces
+(fd=0 gets re-used for sockets in that case).
+
+The patch was imported from the Connman git repository
+(git://git.kernel.org/pub/scm/network/connman) as of commit id
+c7f4151fb053b0d0691d8f10d7e3690265d28889.

+Subject: [PATCH] Fix protocol minor version fall-back
+
+mount.nfs currently expects mount(2) to fail with EPROTONOSUPPORT if
+the kernel doesn't understand the requested NFS version.
+
+Unfortunately if the requested minor is not known to the kernel
+it returns -EINVAL.
+In kernels since 3.11 this can happen in nfs4_alloc_client(), if
+compiled without NFS_V4_2.
+
+More generally it can happen in in nfs_validate_text_mount_data()
+when nfs_parse_mount_options() returns 0 because
+nfs_parse_version_string()
+didn't recognise the version.
+
+EPROTONOSUPPORT is only returned if NFSv4 support is completely compiled
+out.
+
+So nfs_autonegotiate needs to check for EINVAL as well as
+EPROTONOSUPPORT.

+Subject: [PATCH] ifupdown: pass interface device name for ipv6 route commands
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 028524317d8d0011ed38e86e507a06738a5b5a97 from upstream
+
+IPv6 routes need the device argument for link-local routes, or they
+cannot be used at all. E.g. "gateway fe80::def" seems to be used in
+some places, but kernel refuses to insert the route unless device
+name is explicitly specified in the route addition.

+Subject: [PATCH v2] libiproute: handle table ids larger than 255
+
+Linux kernel, starting from 2.6.19 allows ip table ids to have 32-bit values.
+In order to preserve compatibility, the old 8-bit field: rtm_table is still
+in use when table id is lower than 256.
+
+Add support for the 32-bit table id (RTA_TABLE attribute) in:
+- ip route print
+- ip route modify
+- ip rule print
+- ip rule modify
+
+Add printing of table ids to ip route.
+
+Changes are compatible with the mainline iproute2 utilities.
+
+These changes are required for compatibility with ConnMan, which by default
+uses table ids greater than 255.

+busybox1.24.1: Fix busybox - (local) cmdline stack buffer overwrite 
+
+[No upstream tracking] -- https://bugs.busybox.net/show_bug.cgi?id=9071
+
+busybox - (local) cmdline stack buffer overwrite 
+
+Busybox provides an `arp` applet which is missing an array bounds check for 
+command-line parameter `IFNAME`. It is therefore vulnerable to a command-line 
+based local stack buffer overwrite effectively allowing local users to write 
+past a 16 bytes fixed stack buffer. This leads to two scenarios, one (A) where 
+an IOCTL for GET_HW_ADDRESS (`SIOCGIFHWADDR`) fails and results in a corrupted 
+`va_list` being passed to `*printf()` and one (B) where an attacker might provide 
+valid params for the IOCTL and trick the program to proceed and result in a 
+`RET eip overwrite` eventually gaining code execution.
+

+busybox1.24.1: Fix CVE-2016-6301
+
+[No upstream tracking] -- https://bugzilla.redhat.com/show_bug.cgi?id=1363710
+
+ntpd: NTP server denial of service flaw
+
+The busybox NTP implementation doesn't check the NTP mode of packets
+received on the server port and responds to any packet with the right
+size. This includes responses from another NTP server. An attacker can
+send a packet with a spoofed source address in order to create an
+infinite loop of responses between two busybox NTP servers. Adding
+more packets to the loop increases the traffic between the servers
+until one of them has a fully loaded CPU and/or network.
+

+Subject: [PATCH 3/6] Add pretty printers for the NPTL lock types
+
+This patch adds pretty printers for the following NPTL types:
+
+- pthread_mutex_t
+- pthread_mutexattr_t
+- pthread_cond_t
+- pthread_condattr_t
+- pthread_rwlock_t
+- pthread_rwlockattr_t
+
+To load the pretty printers into your gdb session, do the following:
+
+python
+import sys
+sys.path.insert(0, '/path/to/glibc/build/nptl/pretty-printers')
+end
+
+source /path/to/glibc/source/pretty-printers/nptl-printers.py
+
+You can check which printers are registered and enabled by issuing the
+'info pretty-printer' gdb command. Printers should trigger automatically when
+trying to print a variable of one of the types mentioned above.
+
+The printers are architecture-independent, and were tested on an AMD64 running
+Ubuntu 14.04 and an x86 VM running Fedora 24.
+
+In order to work, the printers need to know the values of various flags that
+are scattered throughout pthread.h and pthreadP.h as enums and #defines. Since
+replicating these constants in the printers file itself would create a
+maintenance burden, I wrote a script called gen-py-const.awk that Makerules uses
+to extract the constants. This script is pretty much the same as gen-as-const.awk,
+except it doesn't cast the constant values to 'long' and is thorougly documented.
+The constants need only to be enumerated in a .pysym file, which is then referenced
+by a Make variable called gen-py-const-headers.
+
+As for the install directory, I discussed this with Mike Frysinger and Siddhesh
+Poyarekar, and we agreed that it can be handled in a separate patch, and shouldn't
+block merging of this one.
+
+In addition, I've written a series of test cases for the pretty printers.
+Each lock type (mutex, condvar and rwlock) has two test programs, one for itself
+and other for its related 'attributes' object. Each test program in turn has a
+PExpect-based Python script that drives gdb and compares its output to the
+expected printer's. The tests run on the glibc host, which is assumed to have
+both gdb and PExpect; if either is absent the tests will fail with code 77
+(UNSUPPORTED). For cross-testing you should use cross-test-ssh.sh as test-wrapper.
+I've tested the printers on both native builds and a cross build using a Beaglebone
+Black running Debian, with the build system's filesystem shared with the board
+through NFS.
+
+Finally, I've written a README that explains all this and more.
+

++README for the glibc Python pretty printers
++===========================================
++
++Pretty printers are gdb extensions that allow it to print useful, human-readable
++information about a program's variables.  For example, for a pthread_mutex_t
++gdb would usually output something like this:
++
++(gdb) print mutex
++$1 = {
++  __data = {
++    __lock = 22020096,
++    __count = 0,
++    __owner = 0,
++    __nusers = 0,
++    __kind = 576,
++    __spins = 0,
++    __elision = 0,
++    __list = {
++      __prev = 0x0,
++      __next = 0x0
++    }
++  },
++  __size = "\000\000P\001", '\000' <repeats 12 times>, "@\002", '\000' <repeats 21 times>,
++  __align = 22020096
++}
++
++However, with a pretty printer gdb will output something like this:
++
++(gdb) print mutex
++$1 = pthread_mutex_t = {
++  Type = Normal,
++  Status = Unlocked,
++  Robust = No,
++  Shared = No,
++  Protocol = Priority protect,
++  Priority ceiling = 42
++}
++
++Before printing a value, gdb will first check if there's a pretty printer
++registered for it.  If there is, it'll use it, otherwise it'll print the value
++as usual.  Pretty printers can be registered in various ways; for our purposes
++we register them for the current objfile by calling
++gdb.printing.register_pretty_printer().
++
++Currently our printers are based on gdb.RegexpCollectionPrettyPrinter, which
++means they'll be triggered if the type of the variable we're printing matches
++a given regular expression.  For example, MutexPrinter will be triggered if
++our variable's type matches the regexp '^pthread_mutex_t$'.
++
++Besides the printers themselves, each module may have a constants file which the
++printers will import.  These constants are generated from C headers during the
++build process, and need to be in the Python search path when loading the
++printers.
++
++
++Installing and loading
++----------------------
++
++The pretty printers and their constant files may be installed in different paths
++for each distro, though gdb should be able to automatically load them by itself.
++When in doubt, you can use the 'info pretty-printer' gdb command to list the
++loaded pretty printers.
++
++If the printers aren't automatically loaded for some reason, you should add the
++following to your .gdbinit:
++
++python
++import sys
++sys.path.insert(0, '/path/to/constants/file/directory')
++end
++
++source /path/to/printers.py
++
++If you're building glibc manually, '/path/to/constants/file/directory' should be
++'/path/to/glibc-build/submodule', where 'submodule' is e.g. nptl.
++
++
++Testing
++-------
++
++The pretty printers come with a small test suite based on PExpect, which is a
++Python module with Expect-like features for spawning and controlling interactive
++programs.  Each printer has a corresponding C program and a Python script
++that uses PExpect to drive gdb through the program and compare its output to
++the expected printer's.
++
++The tests run on the glibc host, which is assumed to have both gdb and PExpect;
++if any of those is absent the tests will fail with code 77 (UNSUPPORTED).
++Native builds can be tested simply by doing 'make check'; cross builds must use
++cross-test-ssh.sh as test-wrapper, like this:
++
++make test-wrapper='/path/to/scripts/cross-test-ssh.sh user@host' check
++
++(Remember to share the build system's filesystem with the glibc host's through
++NFS or something similar).
++
++Running 'make check' on a cross build will only compile the test programs,
++without running the scripts.
++
++
++Adding new pretty printers
++--------------------------
++
++Adding new pretty printers to glibc requires following these steps:
++
++1. Identify which constants must be generated from C headers, and write the
++corresponding .pysym file.  See scripts/gen-py-const.awk for more information
++on how this works.  The name of the .pysym file must be added to the
++'gen-py-const-headers' variable in your submodule's Makefile (without the .pysym
++extension).
++
++2. Write the pretty printer code itself.  For this you can follow the gdb
++Python API documentation, and use the existing printers as examples.  The printer
++code must import the generated constants file (which will have the same name
++as your .pysym file).  The names of the pretty printer files must be added
++to the 'pretty-printers' variable in your submodule's Makefile (without the .py
++extension).
++
++3. Write the unit tests for your pretty printers.  The build system calls each
++test script passing it the paths to the test program source, the test program
++binary, and the printer files you added to 'pretty-printers' in the previous
++step.  The test scripts, in turn, must import scripts/test_printers_common
++and call the init_test function passing it, among other things, the name of the
++set of pretty printers to enable (as seen by running 'info pretty-printer').
++You can use the existing unit tests as examples.
++
++4. Add the names of the pretty printer tests to the 'tests-printers' variable
++in your submodule's Makefile (without extensions).  In addition, for each test
++program you must define a corresponding CFLAGS-* variable and set it to
++$(CFLAGS-printers-tests) to ensure they're compiled correctly.  For example,
++test-foo-printer.c requires the following:
++
++CFLAGS-test-foo-printer.c := $(CFLAGS-printers-tests)
++
++Finally, if your programs need to be linked with a specific library, you can add
++its name to the 'tests-printers-libs' variable in your submodule's Makefile.
++
++
++Known issues
++------------
++
++* Pretty printers are inherently coupled to the code they're targetting, thus
++any changes to the target code must also update the corresponding printers.
++On the plus side, the printer code itself may serve as a kind of documentation
++for the target code.
++
++* Older versions of the gdb Python API have a bug where
++gdb.RegexpCollectionPrettyPrinter would not be able to get a value's real type
++if it was typedef'd.  This would cause gdb to ignore the pretty printers for
++types like pthread_mutex_t, which is defined as:
++
++typedef union
++{
++  ...
++} pthread_mutex_t;
++
++This was fixed in commit 1b588015839caafc608a6944a78aea170f5fb2f6, and released
++as part of gdb 7.8.  However, typedef'ing an already typedef'd type may cause
++a similar issue, e.g.:
++
++typedef pthread_mutex_t mutex;
++mutex a_mutex;
++
++Here, trying to print a_mutex won't trigger the pthread_mutex_t printer.
++
++* The test programs must be compiled without optimizations.  This is necessary
++because the test scripts rely on the C code structure being preserved when
++stepping through the programs.  Things like aggressive instruction reordering
++or optimizing variables out may make this kind of testing impossible.

++
++# This script is a smaller version of the clever gen-asm-const.awk hack used to
++# generate ASM constants from .sym files.  We'll use this to generate constants
++# for Python pretty printers.
++#
++# The input to this script are .pysym files that look like:
++# #C_Preprocessor_Directive...
++# NAME1
++# NAME2 expression...
++#
++# A line giving just a name implies an expression consisting of just that name.
++# Comments start with '--'.
++#
++# The output of this script is a 'dummy' function containing 'asm' declarations
++# for each non-preprocessor line in the .pysym file.  The expression values
++# will appear as input operands to the 'asm' declaration.  For example, if we
++# have:
++#
++# /* header.h */
++# #define MACRO 42
++#
++# struct S {
++#     char c1;
++#     char c2;
++#     char c3;
++# };
++#
++# enum E {
++#     ZERO,
++#     ONE
++# };
++#
++# /* symbols.pysym */
++# #include <stddef.h>
++# #include "header.h"
++# -- This is a comment
++# MACRO
++# C3_OFFSET offsetof(struct S, c3)
++# E_ONE ONE
++#
++# the output will be:
++#
++# #include <stddef.h>
++# #include "header.h"
++# void dummy(void)
++# {
++#   asm ("@name@MACRO@value@%0@" : : "i" (MACRO));
++#   asm ("@name@C3_OFFSET@value@%0@" : : "i" (offsetof(struct S, c3)));
++#   asm ("@name@E_ONE@value@%0@" : : "i" (ONE));
++# }
++#
++# We'll later feed this output to gcc -S.  Since '-S' tells gcc to compile but
++# not assemble, gcc will output something like:
++#
++# dummy:
++# 	...
++# 	@name@MACRO@value@$42@
++# 	@name@C3_OFFSET@value@$2@
++# 	@name@E_ONE@value@$1@
++#
++# Finally, we can process that output to extract the constant values.
++# Notice gcc may prepend a special character such as '$' to each value.
++
++# found_symbol indicates whether we found a non-comment, non-preprocessor line.
++BEGIN { found_symbol = 0 }

+Subject: [PATCH 4/6] New condvar implementation that provides stronger
+ ordering guarantees.
+
+This is a new implementation for condition variables, required
+after http://austingroupbugs.net/view.php?id=609 to fix bug 13165.  In
+essence, we need to be stricter in which waiters a signal or broadcast
+is required to wake up; this couldn't be solved using the old algorithm.
+ISO C++ made a similar clarification, so this also fixes a bug in
+current libstdc++, for example.
+
+We can't use the old algorithm anymore because futexes do not guarantee
+to wake in FIFO order.  Thus, when we wake, we can't simply let any
+waiter grab a signal, but we need to ensure that one of the waiters
+happening before the signal is woken up.  This is something the previous
+algorithm violated (see bug 13165).
+
+There's another issue specific to condvars: ABA issues on the underlying
+futexes.  Unlike mutexes that have just three states, or semaphores that
+have no tokens or a limited number of them, the state of a condvar is
+the *order* of the waiters.  A waiter on a semaphore can grab a token
+whenever one is available; a condvar waiter must only consume a signal
+if it is eligible to do so as determined by the relative order of the
+waiter and the signal.
+Therefore, this new algorithm maintains two groups of waiters: Those
+eligible to consume signals (G1), and those that have to wait until
+previous waiters have consumed signals (G2).  Once G1 is empty, G2
+becomes the new G1.  64b counters are used to avoid ABA issues.
+
+This condvar doesn't yet use a requeue optimization (ie, on a broadcast,
+waking just one thread and requeueing all others on the futex of the
+mutex supplied by the program).  I don't think doing the requeue is
+necessarily the right approach (but I haven't done real measurements
+yet):
+* If a program expects to wake many threads at the same time and make
+that scalable, a condvar isn't great anyway because of how it requires
+waiters to operate mutually exclusive (due to the mutex usage).  Thus, a
+thundering herd problem is a scalability problem with or without the
+optimization.  Using something like a semaphore might be more
+appropriate in such a case.
+* The scalability problem is actually at the mutex side; the condvar
+could help (and it tries to with the requeue optimization), but it
+should be the mutex who decides how that is done, and whether it is done
+at all.
+* Forcing all but one waiter into the kernel-side wait queue of the
+mutex prevents/avoids the use of lock elision on the mutex.  Thus, it
+prevents the only cure against the underlying scalability problem
+inherent to condvars.
+* If condvars use short critical sections (ie, hold the mutex just to
+check a binary flag or such), which they should do ideally, then forcing
+all those waiter to proceed serially with kernel-based hand-off (ie,
+futex ops in the mutex' contended state, via the futex wait queues) will
+be less efficient than just letting a scalable mutex implementation take
+care of it.  Our current mutex impl doesn't employ spinning at all, but
+if critical sections are short, spinning can be much better.
+* Doing the requeue stuff requires all waiters to always drive the mutex
+into the contended state.  This leads to each waiter having to call
+futex_wake after lock release, even if this wouldn't be necessary.

++/* We use two 64b counters: __wseq and __g1_start.  They are monotonically
++   increasing and single-writer-multiple-readers counters, so we can implement
++   load, fetch-and-add, and fetch-and-xor operations even when we just have
++   32b atomics.  Values we add or xor are less than or equal to 1<<31 (*),
++   so we only have to make overflow-and-addition atomic wrt. to concurrent
++   load operations and xor operations.  To do that, we split each counter into
++   two 32b values of which we reserve the MSB of each to represent an
++   overflow from the lower-order half to the higher-order half.
++
++   In the common case, the state is (higher-order / lower-order half, and . is
++   basically concatenation of the bits):
++   0.h     / 0.l  = h.l
++
++   When we add a value of x that overflows (i.e., 0.l + x == 1.L), we run the
++   following steps S1-S4 (the values these represent are on the right-hand
++   side):
++   S1:  0.h     / 1.L == (h+1).L
++   S2:  1.(h+1) / 1.L == (h+1).L
++   S3:  1.(h+1) / 0.L == (h+1).L
++   S4:  0.(h+1) / 0.L == (h+1).L
++   If the LSB of the higher-order half is set, readers will ignore the
++   overflow bit in the lower-order half.
++
++   To get an atomic snapshot in load operations, we exploit that the
++   higher-order half is monotonically increasing; if we load a value V from
++   it, then read the lower-order half, and then read the higher-order half
++   again and see the same value V, we know that both halves have existed in
++   the sequence of values the full counter had.  This is similar to the
++   validated reads in the time-based STMs in GCC's libitm (e.g.,
++   method_ml_wt).
++
++   The xor operation needs to be an atomic read-modify-write.  The write
++   itself is not an issue as it affects just the lower-order half but not bits
++   used in the add operation.  To make the full fetch-and-xor atomic, we
++   exploit that concurrently, the value can increase by at most 1<<31 (*): The
++   xor operation is only called while having acquired the lock, so not more
++   than __PTHREAD_COND_MAX_GROUP_SIZE waiters can enter concurrently and thus
++   increment __wseq.  Therefore, if the xor operation observes a value of
++   __wseq, then the value it applies the modification to later on can be
++   derived (see below).
++
++   One benefit of this scheme is that this makes load operations
++   obstruction-free because unlike if we would just lock the counter, readers
++   can almost always interpret a snapshot of each halves.  Readers can be
++   forced to read a new snapshot when the read is concurrent with an overflow.
++   However, overflows will happen infrequently, so load operations are
++   practically lock-free.
++
++   (*) The highest value we add is __PTHREAD_COND_MAX_GROUP_SIZE << 2 to
++   __g1_start (the two extra bits are for the lock in the two LSBs of
++   __g1_start).  */

++   acquiring the mutex) happen in some total order that is consistent with the
++   happens-before relations in the calling program.  However, this order does
++   not necessarily result in additional happens-before relations being
++   established (which aligns well with spurious wake-ups being allowed).
++
++   All waiters acquire a certain position in a 64b waiter sequence (__wseq).
++   This sequence determines which waiters are allowed to consume signals.
++   A broadcast is equal to sending as many signals as are unblocked waiters.
++   When a signal arrives, it samples the current value of __wseq with a
++   relaxed-MO load (i.e., the position the next waiter would get).  (This is
++   sufficient because it is consistent with happens-before; the caller can
++   enforce stronger ordering constraints by calling signal while holding the
++   mutex.)  Only waiters with a position less than the __wseq value observed
++   by the signal are eligible to consume this signal.
++
++   This would be straight-forward to implement if waiters would just spin but
++   we need to let them block using futexes.  Futexes give no guarantee of
++   waking in FIFO order, so we cannot reliably wake eligible waiters if we
++   just use a single futex.  Also, futex words are 32b in size, but we need
++   to distinguish more than 1<<32 states because we need to represent the
++   order of wake-up (and thus which waiters are eligible to consume signals);
++   blocking in a futex is not atomic with a waiter determining its position in
++   the waiter sequence, so we need the futex word to reliably notify waiters
++   that they should not attempt to block anymore because they have been
++   already signaled in the meantime.  While an ABA issue on a 32b value will
++   be rare, ignoring it when we are aware of it is not the right thing to do
++   either.
++
++   Therefore, we use a 64b counter to represent the waiter sequence (on
++   architectures which only support 32b atomics, we use a few bits less).
++   To deal with the blocking using futexes, we maintain two groups of waiters:
++   * Group G1 consists of waiters that are all eligible to consume signals;
++     incoming signals will always signal waiters in this group until all
++     waiters in G1 have been signaled.
++   * Group G2 consists of waiters that arrive when a G1 is present and still
++     contains waiters that have not been signaled.  When all waiters in G1
++     are signaled and a new signal arrives, the new signal will convert G2
++     into the new G1 and create a new G2 for future waiters.
++
++   We cannot allocate new memory because of process-shared condvars, so we
++   have just two slots of groups that change their role between G1 and G2.
++   Each has a separate futex word, a number of signals available for
++   consumption, a size (number of waiters in the group that have not been
++   signaled), and a reference count.
++
++   The group reference count is used to maintain the number of waiters that
++   are using the group's futex.  Before a group can change its role, the
++   reference count must show that no waiters are using the futex anymore; this
++   prevents ABA issues on the futex word.
++
++   To represent which intervals in the waiter sequence the groups cover (and
++   thus also which group slot contains G1 or G2), we use a 64b counter to
++   designate the start position of G1 (inclusive), and a single bit in the
++   waiter sequence counter to represent which group slot currently contains
++   G2.  This allows us to switch group roles atomically wrt. waiters obtaining
++   a position in the waiter sequence.  The G1 start position allows waiters to
++   figure out whether they are in a group that has already been completely
++   signaled (i.e., if the current G1 starts at a later position that the
++   waiter's position).  Waiters cannot determine whether they are currently
++   in G2 or G1 -- but they do not have too because all they are interested in
++   is whether there are available signals, and they always start in G2 (whose
++   group slot they know because of the bit in the waiter sequence.  Signalers
++   will simply fill the right group until it is completely signaled and can
++   be closed (they do not switch group roles until they really have to to
++   decrease the likelihood of having to wait for waiters still holding a
++   reference on the now-closed G1).
++
++   Signalers maintain the initial size of G1 to be able to determine where
++   G2 starts (G2 is always open-ended until it becomes G1).  They track the
++   remaining size of a group; when waiters cancel waiting (due to PThreads
++   cancellation or timeouts), they will decrease this remaining size as well.
++
++   To implement condvar destruction requirements (i.e., that
++   pthread_cond_destroy can be called as soon as all waiters have been
++   signaled), waiters increment a reference count before starting to wait and
++   decrement it after they stopped waiting but right before they acquire the
++   mutex associated with the condvar.
++
++   pthread_cond_t thus consists of the following (bits that are used for
++   flags and are not part of the primary value of each field but necessary
++   to make some things atomic or because there was no space for them
++   elsewhere in the data structure):
++
++   __wseq: Waiter sequence counter
++     * LSB is index of current G2.
++     * Waiters fetch-add while having acquire the mutex associated with the
++       condvar.  Signalers load it and fetch-xor it concurrently.
++   __g1_start: Starting position of G1 (inclusive)
++     * LSB is index of current G2.
++     * Modified by signalers while having acquired the condvar-internal lock
++       and observed concurrently by waiters.
++   __g1_orig_size: Initial size of G1
++     * The two least-significant bits represent the condvar-internal lock.
++     * Only accessed while having acquired the condvar-internal lock.
++   __wrefs: Waiter reference counter.
++     * Bit 2 is true if waiters should run futex_wake when they remove the
++       last reference.  pthread_cond_destroy uses this as futex word.
++     * Bit 1 is the clock ID (0 == CLOCK_REALTIME, 1 == CLOCK_MONOTONIC).
++     * Bit 0 is true iff this is a process-shared condvar.
++     * Simple reference count used by both waiters and pthread_cond_destroy.
++     (If the format of __wrefs is changed, update nptl_lock_constants.pysym
++      and the pretty printers.)
++   For each of the two groups, we have:
++   __g_refs: Futex waiter reference count.
++     * LSB is true if waiters should run futex_wake when they remove the
++       last reference.
++     * Reference count used by waiters concurrently with signalers that have
++       acquired the condvar-internal lock.
++   __g_signals: The number of signals that can still be consumed.
++     * Used as a futex word by waiters.  Used concurrently by waiters and
++       signalers.
++     * LSB is true iff this group has been completely signaled (i.e., it is
++       closed).
++   __g_size: Waiters remaining in this group (i.e., which have not been
++     signaled yet.
++     * Accessed by signalers and waiters that cancel waiting (both do so only
++       when having acquired the condvar-internal lock.
++     * The size of G2 is always zero because it cannot be determined until
++       the group becomes G1.
++     * Although this is of unsigned type, we rely on using unsigned overflow
++       rules to make this hold effectively negative values too (in
++       particular, when waiters in G2 cancel waiting).
++
++   A PTHREAD_COND_INITIALIZER condvar has all fields set to zero, which yields
++   a condvar that has G2 starting at position 0 and a G1 that is closed.
++
++   Because waiters do not claim ownership of a group right when obtaining a
++   position in __wseq but only reference count the group when using futexes
++   to block, it can happen that a group gets closed before a waiter can
++   increment the reference count.  Therefore, waiters have to check whether
++   their group is already closed using __g1_start.  They also have to perform
++   this check when spinning when trying to grab a signal from __g_signals.
++   Note that for these checks, using relaxed MO to load __g1_start is
++   sufficient because if a waiter can see a sufficiently large value, it could
++   have also consume a signal in the waiters group.
++
++   Waiters try to grab a signal from __g_signals without holding a reference
++   count, which can lead to stealing a signal from a more recent group after
++   their own group was already closed.  They cannot always detect whether they
++   in fact did because they do not know when they stole, but they can
++   conservatively add a signal back to the group they stole from; if they
++   did so unnecessarily, all that happens is a spurious wake-up.  To make this
++   even less likely, __g1_start contains the index of the current g2 too,
++   which allows waiters to check if there aliasing on the group slots; if
++   there wasn't, they didn't steal from the current G1, which means that the
++   G1 they stole from must have been already closed and they do not need to
++   fix anything.
++
++   It is essential that the last field in pthread_cond_t is __g_signals[1]:
++   The previous condvar used a pointer-sized field in pthread_cond_t, so a
++   PTHREAD_COND_INITIALIZER from that condvar implementation might only
++   initialize 4 bytes to zero instead of the 8 bytes we need (i.e., 44 bytes
++   in total instead of the 48 we need).  __g_signals[1] is not accessed before
++   the first group switch (G2 starts at index 0), which will set its value to
++   zero after a harmless fetch-or whose return value is ignored.  This
++   effectively completes initialization.
++
++
++   Limitations:
++   * This condvar isn't designed to allow for more than
++     __PTHREAD_COND_MAX_GROUP_SIZE * (1 << 31) calls to __pthread_cond_wait.
++   * More than __PTHREAD_COND_MAX_GROUP_SIZE concurrent waiters are not
++     supported.
++   * Beyond what is allowed as errors by POSIX or documented, we can also
++     return the following errors:
++     * EPERM if MUTEX is a recursive mutex and the caller doesn't own it.
++     * EOWNERDEAD or ENOTRECOVERABLE when using robust mutexes.  Unlike
++       for other errors, this can happen when we re-acquire the mutex; this
++       isn't allowed by POSIX (which requires all errors to virtually happen
++       before we release the mutex or change the condvar state), but there's
++       nothing we can do really.
++     * When using PTHREAD_MUTEX_PP_* mutexes, we can also return all errors
++       returned by __pthread_tpp_change_priority.  We will already have
++       released the mutex in such cases, so the caller cannot expect to own
++       MUTEX.
++
++   Other notes:
++   * Instead of the normal mutex unlock / lock functions, we use
++     __pthread_mutex_unlock_usercnt(m, 0) / __pthread_mutex_cond_lock(m)
++     because those will not change the mutex-internal users count, so that it
++     can be detected when a condvar is still associated with a particular
++     mutex because there is a waiter blocked on this condvar using this mutex.

+Subject: [PATCH 5/6] Remove __ASSUME_REQUEUE_PI
+
+The new cond var implementation (ed19993b5b0d) removed all the
+__ASSUME_{REQUEUE_PI,FUTEX_LOCK_PI} internal usage so there is no
+need to keep defining it.  This patch removes all USE_REQUEUE_PI
+and __ASSUME_REQUEUE_PI.  It is as follow up from BZ#18463.
+
+Checked with a build for x86_64-linux-gnu, arm-linux-gnueabhf,
+m68-linux-gnu, mips64-linux-gnu, and sparc64-linux-gnu.
+
+    * nptl/pthreadP.h (USE_REQUEUE_PI): Remove ununsed macro.
+    * sysdeps/unix/sysv/linux/arm/kernel-features.h
+    (__ASSUME_REQUEUE_PI): Likewise.
+    * sysdeps/unix/sysv/linux/kernel-features.h
+    (__ASSUME_REQUEUE_PI): Likewise.
+    * sysdeps/unix/sysv/linux/m68k/kernel-features.h

+Subject: [PATCH 6/6] Fix atomic_fetch_xor_release.
+
+No code uses atomic_fetch_xor_release except for the upcoming
+conditional variable rewrite. Therefore there is no user
+visible bug here. The use of atomic_compare_and_exchange_bool_rel
+is removed (since it doesn't exist anymore), and is replaced
+by atomic_compare_exchange_weak_release.
+
+We use weak_release because it provides better performance in
+the loop (the weak semantic) and because the xor is release MO
+(the release semantic). We don't reload expected in the loop
+because atomic_compare_and_exchange_weak_release does this for
+us as part of the CAS failure.
+
+It is otherwise a fairly plain conversion that fixes building
+the new condvar for 32-bit x86. Passes all regression tests
+for x86.

+Subject: [PATCH] Bug 20116: Fix use after free in pthread_create()
+
+The commit documents the ownership rules around 'struct pthread' and
+when a thread can read or write to the descriptor. With those ownership
+rules in place it becomes obvious that pd->stopped_start should not be
+touched in several of the paths during thread startup, particularly so
+for detached threads. In the case of detached threads, between the time
+the thread is created by the OS kernel and the creating thread checks
+pd->stopped_start, the detached thread might have already exited and the
+memory for pd unmapped. As a regression test we add a simple test which
+exercises this exact case by quickly creating detached threads with
+large enough stacks to ensure the thread stack cache is bypassed and the
+stacks are unmapped. Before the fix the testcase segfaults, after the
+fix it works correctly and completes without issue.
+
+For a detailed discussion see:
+https://www.sourceware.org/ml/libc-alpha/2017-01/msg00505.html
+

++/* CONCURRENCY NOTES:
++
++   Understanding who is the owner of the 'struct pthread' or 'PD'
++   (refers to the value of the 'struct pthread *pd' function argument)
++   is critically important in determining exactly which operations are
++   allowed and which are not and when, particularly when it comes to the
++   implementation of pthread_create, pthread_join, pthread_detach, and
++   other functions which all operate on PD.
++
++   The owner of PD is responsible for freeing the final resources
++   associated with PD, and may examine the memory underlying PD at any
++   point in time until it frees it back to the OS or to reuse by the
++   runtime.
++
++   The thread which calls pthread_create is called the creating thread.
++   The creating thread begins as the owner of PD.
++
++   During startup the new thread may examine PD in coordination with the
++   owner thread (which may be itself).
++
++   The four cases of ownership transfer are:
++
++   (1) Ownership of PD is released to the process (all threads may use it)
++       after the new thread starts in a joinable state
++       i.e. pthread_create returns a usable pthread_t.
++
++   (2) Ownership of PD is released to the new thread starting in a detached
++       state.
++
++   (3) Ownership of PD is dynamically released to a running thread via
++       pthread_detach.
++
++   (4) Ownership of PD is acquired by the thread which calls pthread_join.
++
++   Implementation notes:
++
++   The PD->stopped_start and thread_ran variables are used to determine
++   exactly which of the four ownership states we are in and therefore
++   what actions can be taken.  For example after (2) we cannot read or
++   write from PD anymore since the thread may no longer exist and the
++   memory may be unmapped.  The most complicated cases happen during
++   thread startup:
++
++   (a) If the created thread is in a detached (PTHREAD_CREATE_DETACHED),
++       or joinable (default PTHREAD_CREATE_JOINABLE) state and
++       STOPPED_START is true, then the creating thread has ownership of
++       PD until the PD->lock is released by pthread_create.  If any
++       errors occur we are in states (c), (d), or (e) below.
++
++   (b) If the created thread is in a detached state
++       (PTHREAD_CREATED_DETACHED), and STOPPED_START is false, then the
++       creating thread has ownership of PD until it invokes the OS
++       kernel's thread creation routine.  If this routine returns
++       without error, then the created thread owns PD; otherwise, see
++       (c) and (e) below.
++
++   (c) If the detached thread setup failed and THREAD_RAN is true, then
++       the creating thread releases ownership to the new thread by
++       sending a cancellation signal.  All threads set THREAD_RAN to
++       true as quickly as possible after returning from the OS kernel's
++       thread creation routine.
++
++   (d) If the joinable thread setup failed and THREAD_RAN is true, then
++       then the creating thread retains ownership of PD and must cleanup
++       state.  Ownership cannot be released to the process via the
++       return of pthread_create since a non-zero result entails PD is
++       undefined and therefore cannot be joined to free the resources.
++       We privately call pthread_join on the thread to finish handling
++       the resource shutdown (Or at least we should, see bug 19511).
++
++   (e) If the thread creation failed and THREAD_RAN is false, then the
++       creating thread retains ownership of PD and must cleanup state.
++       No waiting for the new thread is required because it never
++       started.
++
++   The nptl_db interface:
++
++   The interface with nptl_db requires that we enqueue PD into a linked
++   list and then call a function which the debugger will trap.  The PD
++   will then be dequeued and control returned to the thread.  The caller
++   at the time must have ownership of PD and such ownership remains
++   after control returns to thread. The enqueued PD is removed from the
++   linked list by the nptl_db callback td_thr_event_getmsg.  The debugger
++   must ensure that the thread does not resume execution, otherwise
++   ownership of PD may be lost and examining PD will not be possible.
++
++   Note that the GNU Debugger as of (December 10th 2015) commit
++   c2c2a31fdb228d41ce3db62b268efea04bd39c18 no longer uses
++   td_thr_event_getmsg and several other related nptl_db interfaces. The
++   principal reason for this is that nptl_db does not support non-stop
++   mode where other threads can run concurrently and modify runtime
++   structures currently in use by the debugger and the nptl_db
++   interface.
++
++   Axioms:
++
++   * The create_thread function can never set stopped_start to false.
++   * The created thread can read stopped_start but never write to it.
++   * The variable thread_ran is set some time after the OS thread
++     creation routine returns, how much time after the thread is created
++     is unspecified, but it should be as quickly as possible.

++   new thread to synchronize at startup for some other implementation
++   reason.  If STOPPED_START will be true, then create_thread is obliged
++   to lock PD->lock before starting the thread.  Then pthread_create
++   unlocks PD->lock which synchronizes-with START_THREAD_DEFN in the
++   child thread which does an acquire/release of PD->lock as the last
++   action before calling the user entry point.  The goal of all of this
++   is to ensure that the required initial thread attributes are applied
++   (by the creating thread) before the new thread runs user code.  Note
++   that the the functions pthread_getschedparam, pthread_setschedparam,
++   pthread_setschedprio, __pthread_tpp_change_priority, and
++   __pthread_current_priority reuse the same lock, PD->lock, for a
++   similar purpose e.g. synchronizing the setting of similar thread
++   attributes.  These functions are never called before the thread is
++   created, so don't participate in startup syncronization, but given
++   that the lock is present already and in the unlocked state, reusing
++   it saves space.
+ 
+    The return value is zero for success or an errno code for failure.
+    If the return value is ENOMEM, that will be translated to EAGAIN,
+    so create_thread need not do that.  On failure, *THREAD_RAN should
+    be set to true iff the thread actually started up and then got

+xpointer: Disallow namespace nodes in XPointer points and ranges
+
+Namespace nodes must be copied to avoid use-after-free errors.
+But they don't necessarily have a physical representation in a
+document, so simply disallow them in XPointer ranges.

+From: Nick Wellnhofer <wellnhofer@aevum.de>
+Date: Tue, 28 Jun 2016 14:22:23 +0200
+Subject: [PATCH] Fix XPointer paths beginning with range-to
+
+The old code would invoke the broken xmlXPtrRangeToFunction. range-to
+isn't really a function but a special kind of location step. Remove
+this function and always handle range-to in the XPath code.
+
+The old xmlXPtrRangeToFunction could also be abused to trigger a
+use-after-free error with the potential for remote code execution.
+
+Found with afl-fuzz.
+
+Fixes CVE-2016-5131.
+
+CVE: CVE-2016-5131

+Subject: [PATCH 3/3] core/load-fragment: refuse units with errors in certain
+ directives
+
+If an error is encountered in any of the Exec* lines, WorkingDirectory,
+SELinuxContext, ApparmorProfile, SmackProcessLabel, Service (in .socket
+units), User, or Group, refuse to load the unit. If the config stanza
+has support, ignore the failure if '-' is present.
+
+For those configuration directives, even if we started the unit, it's
+pretty likely that it'll do something unexpected (like write files
+in a wrong place, or with a wrong context, or run with wrong permissions,
+etc). It seems better to refuse to start the unit and have the admin
+clean up the configuration without giving the service a chance to mess
+up stuff.
+
+Note that all "security" options that restrict what the unit can do
+(Capabilities, AmbientCapabilities, Restrict*, SystemCallFilter, Limit*,
+PrivateDevices, Protect*, etc) are _not_ treated like this. Such options are
+only supplementary, and are not always available depending on the architecture
+and compilation options, so unit authors have to make sure that the service
+runs correctly without them anyway.
+
+Fixes #6237, #6277.

+Subject: [PATCH] e2fsck: exit with exit status 0 if no errors were fixed
+
+Previously, e2fsck would exit with a status code of 1 even though the
+only changes that it made to the file system were various
+optimziations and not fixing file system corruption.  Since the man
+page states that an exit status of 1 means "file system errors
+corrupted", fix e2fsck to return an exit status of 0.

+From 09949994e76eea3c1230a5c88ffa8fdf588b120f Mon Sep 17 00:00:00 2001
+From: Mark Wielaard <mjw@redhat.com>
+Date: Wed, 2 Nov 2016 13:29:26 +0100
+Subject: [PATCH] Add GCC7 -Wimplicit-fallthrough support/fixes.
+
+GCC7 will have a new -Wimplicit-fallthrough warning. It did catch one
+small buglet in elflint option procession. So it seems useful to enable
+to make sure all swatch case fallthroughs are deliberate.
+
+Add configure check to detect whether gcc support -Wimplicit-fallthrough
+and enable it. Add fixes and explicit fallthrough comments where necessary.

+Subject: [PATCH] ar: Fix GCC7 -Wformat-length issues.
+
+GCC7 adds warnings for snprintf formatting into too small buffers.
+Fix the two issues pointed out by the new warning. The ar header
+fields are fixed length containing left-justified strings without
+zero terminator. snprintf always adds a '\0' char at the end (which
+we then don't copy into the ar header field) and numbers are decimal
+strings of fixed 10 chars  (-Wformat-length thinks formatting
+them as size_t might overflow the buffer on 64bit arches).

+From: Seebs <seebs@seebs.net>
+Date: Thu, 3 Nov 2016 11:36:12 -0500
+Subject: [PATCH] More-correctly fix xattrs
+
+Fix provided by Patrick Ohly <patrick.ohly@intel.com>. This resolves
+the actual cause of the path length mismatches, and explains why
+I couldn't quite explain why the previous one had only sometimes
+worked, also why it showed up on directories but not plain files.
+
+Signed-off-by: Seebs <seebs@seebs.net>
+
+Fixes [YOCTO #10623]

+Upstream-Status: Backport [commit 45eca34c754d416a38bee90fb2d3c110a0b6cc5f]

+vq->inuse must be zeroed upon device reset like most other virtqueue
+fields.
+
+In theory, virtio_reset() just needs assert(vq->inuse == 0) since
+devices must clean up in-flight requests during reset (requests cannot
+not be leaked!).
+
+In practice, it is difficult to achieve vq->inuse == 0 across reset
+because balloon, blk, 9p, etc implement various different strategies for
+cleaning up requests.  Most devices call g_free(elem) directly without
+telling virtio.c that the VirtQueueElement is cleaned up.  Therefore
+vq->inuse is not decremented during reset.
+
+This patch zeroes vq->inuse and trusts that devices are not leaking
+VirtQueueElements across reset.
+
+I will send a follow-up series that refactors request life-cycle across
+all devices and converts vq->inuse = 0 into assert(vq->inuse == 0) but
+this more invasive approach is not appropriate for stable trees.

+
+When processing IO request in mptsas, it uses g_new to allocate
+a 'req' object. If an error occurs before 'req->sreq' is
+allocated, It could lead to an OOB write in mptsas_free_request
+function. Use g_new0 to avoid it.

+The AMD PC-Net II emulator has set of control and status(CSR)
+registers. Of these, CSR76 and CSR78 hold receive and transmit
+descriptor ring length respectively. This ring length could range
+from 1 to 65535. Setting ring length to zero leads to an infinite

+Similar to what rpm4 has. This macro can be used to customize the
+gpg command line options when signing packages. This is needed for
+gpg 2.1 which requires "--pinentry-mode loopback" to allow
+non-interactive signing.

+Subject: [PATCH] fix "svnadmin create" fail on x86
+
+When run the following command on x86:
+
+        svnadmin create /var/test_repo
+
+It cause segmentation fault error like the following:
+
+        [16499.751837] svnadmin[21117]: segfault at 83 ip 00000000f74bf7f6 sp 00000000ffdd9b34 error 4 in libc-2.24.so[f7441000+1af000]
+        Segmentation fault (core dumped)
+
+This is because in source code ./subversion/libsvn_fs_fs/low_level.c,
+function svn_fs_fs__unparse_footer, when:
+
+        target arch:    x86
+        apr_off_t:      4 bytes
+
+if the "APR_OFF_T_FMT" is "lld", it still use type "apr_off_t" to pass
+data to apr, but in apr source code file apr_snprintf.c the function
+apr_vformatter meet "lld", it would use the:
+
+        i_quad = va_arg(ap, apr_int64_t);
+
+It uses the apr_int64_t to deal data, it read 8 bytes, so the follow-up
+data may be error.

+Hack: Depending on how glibc was compiled (e.g. optimised for size or

+Subject: [PATCH] fix crash with bad data supplied to makeimagedevice
+
+Bug #697450 "Null pointer dereference in gx_device_finalize()"
+
+The problem here is that the code to finalise a device unconditionally
+frees the icc_struct member of the device structure. However this
+particular (weird) device is not setup as a normal device, probably
+because its very, very ancient. Its possible for the initialisation
+of the device to abort with an error before calling gs_make_mem_device()
+which is where the icc_struct member gets allocated (or set to NULL).
+
+If that happens, then the cleanup code tries to free the device, which
+calls finalize() which tries to free a garbage pointer.
+
+Setting the device memory to 0x00 after we allocate it means that the
+icc_struct member will be NULL< and our memory manager allows for that
+happily enough, which avoids the problem.

+Subject: [PATCH] Bug 697548: use the correct param list enumerator
+
+When we encountered dictionary in a ref_param_list, we were using the enumerator
+for the "parent" param_list, rather than the enumerator for the param_list
+we just created for the dictionary. That parent was usually the stack
+list enumerator, and caused a segfault.
+
+Using the correct enumerator works better.

+Subject: [PATCH] Ensure a device has raster memory, before trying to read it.
+
+Bug #697676 "Null pointer dereference in mem_get_bits_rectangle()"
+
+This is only possible by abusing/mis-using Ghostscript-specific
+language extensions, so cannot happen in a general PostScript program.
+
+Nevertheless, Ghostscript should not crash. So this commit checks the
+memory device to see if raster memory has been allocated, before trying
+to read from it.

+Subject: [PATCH] Add configuration option for no input device.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+[Backported from master, 75b7197.]
+
+As it has been discussed in the past [1], running Weston
+without any input device at launch might be beneficial for
+some use cases.
+
+Certainly, it's best for the vast majority of users (and
+the project) to require an input device to be present, as
+to avoid frustration and hassle, but for those brave souls
+that so prefer, this patch lets them run without any input
+device at all.
+
+This introduces a simple configuration in weston.ini:
+  [core]
+  require-input=true
+
+True is the default, so no behavioral change is introduced.

+From 9362c7ddd1af3b168953d0737877bc52d79c94f4 Mon Sep 17 00:00:00 2001
+From: Tobias Stoeckmann <tobias@stoeckmann.org>
+Date: Sun, 25 Sep 2016 21:43:09 +0200
+Subject: Validate lengths while parsing server data.
+
+Individual lengths inside received server data can overflow
+the previously reserved memory.
+
+It is therefore important to validate every single length
+field to not overflow the previously agreed sum of all invidual
+length fields.
+
+v2: consume remaining bytes in the reply buffer on error.

+
+By having the quotes, the kernel Makefile addtree macro adds the

+Removing the quotes resolves the issue.

+This is trimmed from the verbose output of the GCC command line

+An attacker who learns the EdDSA session key from side-channel
+observation during the signing process, can easily revover the long-

+Sliding right into disaster: Left-to-right sliding windows leak
+by Daniel J. Bernstein and Joachim Breitner and Daniel Genkin and
+Leon Groot Bruinderink and Nadia Heninger and Tanja Lange and
+Christine van Vredendaal and Yuval Yarom
+
+  It is well known that constant-time implementations of modular
+  exponentiation cannot use sliding windows. However, software
+  libraries such as Libgcrypt, used by GnuPG, continue to use sliding
+  windows. It is widely believed that, even if the complete pattern of
+  squarings and multiplications is observed through a side-channel
+  attack, the number of exponent bits leaked is not sufficient to
+  carry out a full key-recovery attack against RSA. Specifically,
+  4-bit sliding windows leak only 40% of the bits, and 5-bit sliding
+  windows leak only 33% of the bits.
+
+  In this paper we demonstrate a complete break of RSA-1024 as
+  implemented in Libgcrypt. Our attack makes essential use of the fact
+  that Libgcrypt uses the left-to-right method for computing the
+  sliding-window expansion. We show for the first time that the
+  direction of the encoding matters: the pattern of squarings and
+  multiplications in left-to-right sliding windows leaks significantly
+  more information about exponent bits than for right-to-left. We show
+  how to incorporate this additional information into the
+  Heninger-Shacham algorithm for partial key reconstruction, and use
+  it to obtain very efficient full key recovery for RSA-1024. We also
+  provide strong evidence that the same attack works for RSA-2048 with
+  only moderately more computation.
+
+Exponent blinding is a kind of workaround to add noise.  Signal (leak)
+is still there for non-constant-time implementation.
