* musl: Fix CVE-2019-14697Hauke Mehrtens2019-08-182-0/+207
| | | | | | | | | | | musl libc through 1.1.23 has an x87 floating-point stack adjustment imbalance, related to the math/i386/ directory. In some cases, use of this library could introduce out-of-bounds writes that are not present in an application's source code. This problem only affects x86 and no other architectures.

* musl: ldso/dlsym: fix mips returning undef dlsymLuiz Angelo Daros de Luca2019-08-171-0/+136
| | | | | | | | | | | | | | | This happens only the second time a library is loaded by dlopen(). After lib1 is loaded, dlsym(lib1,"undef1") correctly resolves the undef symbol from lib1 dependencies. After the second library is loaded, dlsym(lib2,"undef1") was returning the address of "undef1" in lib2 instead of searching lib2 dependencies. Using upstream fix which now uses the same logic for relocation time and dlsym. Fixes openwrt/packages#9297 Signed-off-by: Luiz Angelo Daros de Luca <luizluca@gmail.com>

* toolchain/musl: update to version 1.1.21Christian Lamparter2019-02-052-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | <https://www.openwall.com/lists/musl/2019/01/21/8> "This release makes improvements with respect to default thread stack size, including increasing the default from 80k to 128k, increasing the default guard size from 4k to 8k, and allowing the default to be increased via ELF headers so that programs that need larger stacks can be build without source-level changes, using just LDFLAGS. Insufficient stack size for AIO threads on kernels that don't honor the constant MINSIGSTKSZ is also fixed. The glob core has been rewritten to fix inability to see past searchable-but-unreadable path components, and to avoid excessive stack usage and unnecessary syscalls. The tsearch AVL tree implementation has also been rewritten for better size and performance. The math library adds more native single-instruction implementations for arm, s390x, powerpc, and x86_64. Various bugs are fixed, including several possible deadlocks, one of which was a new regression in 1.1.20." detailed release notes can be found in the WHATSNEW file: <http://git.musl-libc.org/cgit/musl/tree/WHATSNEW#n1989> Tested-by: Koen Vandeputte <koen.vandeputte@ncentric.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
* musl: improve crypt() size hackJo-Philipp Wich2019-01-221-25/+40
| | | | | | | | | | | | | | Instead of silently downgrading any non-MD5 crypt() request to DES, cleanly fail with return NULL and errno = ENOSYS. This allows callers to notice the missing support instead of the unwanted silent fallback to DES. Also add a menuconfig toolchain option to optionally disable the crypt size hack completely. This can be probably made dependant on SMALL_FLASH or a similar feature indicator in a future commit. Ref: https://github.com/openwrt/openwrt/pull/1331 Signed-off-by: Jo-Philipp Wich <jo@mein.io>
* toolchain/musl: update to version 1.1.20Christian Lamparter2018-09-215-85/+29
| | | | | | | | | | | | | | | | | | | | | | | This release introduces the ability to replace/interpose the allocator (malloc) subject to certain restrictions, adds an experimental m68k port, and makes notable improvements to stdio (application-provided buffers), getaddrinfo (AI_ADDRCONFIG, support for IPv4-only kernel configurations), the dynamic linker (safety against dlopen of libraries using initial-exec TLS model, reclaiming unused memory on FDPIC archs, better dladdr results), and handling of default thread stack size (pthread_setattr_default_np now works more reliably). Many bugs have been fixed, including potentially dangerous regressions in iconv (only for new conversions to legacy encodings) and visibly incorrect behavior in printf on non-x86 archs (%a format with precision specifier), in getopt_long_only when short options are a prefix for a long option, in complex arc-trig/hyperbolic functions, in strftime and mktime (timezone-specific issues), and numerous less-obvious places.

| | | | | | | | | | | | | | | | | | | | | This patch updates musl to 1.1.16+ [0] and removes all the backported patches. This is a major release and tagged as such. For more information visit musl-libc.org or read the WHATSNEW. Furthermore, this patch also changes musl to download directly from git. This makes it easier to update musl in the future. The patch custom Add-format-attribute-to-some-function-declarations.patch was assigned a new 400- number. This should avoid confusion since 0xx numbers are usually assigned to backports.

* musl: Add format attribute to some function declarationsHauke Mehrtens2016-01-241-0/+209
| | | | | | | | | | | | | | | | | | | | | | | | | GCC and Clang are able to check the format arguments given to a function and warn the user if there is a error in the format arguments or if there is a potential uncontrolled format string security problem in the code. GCC does this automatically for some functions like printf(), but it is also possible to annotate other functions in a way that it will check them too. This feature is used by glibc for many functions. This patch adds the attribute to the some functions of musl expect for these functions where gcc automatically adds it. GCC automatically adds checks for these functions: printf, fprintf, sprintf, scanf, fscanf, sscanf, strftime, vprintf, vfprintf and vsprintf.

* musl: read the timezone from /etc/TZFelix Fietkau2015-06-191-0/+28
| | | | | | | | | | | | | | | | | | | | | | Currently the OpenWRT boot scripts write the timezone configuration to /tmp/TZ, relying on the behaviour of uClibc that the timezone is read from /etc/TZ if no TZ env variable is found. This works because /etc/TZ is a symlink to /tmp/TZ. Musl libc however only reads the timezone from the TZ env variable and if it doesn't find it or it's empty, it will look for a zoneinfo file, that doesn't exist. So in musl builds no timezone is ever set. This patch fixes the issue by having musl libc behave like uClibc: if no TZ env variable is found it will try to load it from /etc/TZ.
