Updated lists after reviewing the list and pushing the changes that
were easy to make/merge:
Still pending due to nontrivial patch to review and/or need for
testing:
- getenv/setenv/putenv ub
http://www.openwall.com/lists/musl/2017/08/21/1
http://www.openwall.com/lists/musl/2016/03/13/7
- mbsnrtowcs and mbsnrtowcs confuses byte and wchar counts
http://www.openwall.com/lists/musl/2017/08/09/1
- oob reads in memmem (and signed << ub)
http://www.openwall.com/lists/musl/2017/06/29/6
- fix nftw when called with paths ending in slash
http://www.openwall.com/lists/musl/2017/03/07/1
Pending due to waiting for updated patch incorporating feedback
already given or resolving merge conflicts or similar:
- handle whitespace before %% in scanf
http://www.openwall.com/lists/musl/2017/07/11/1
- make dlsym and reloc time lookup consistent
http://www.openwall.com/lists/musl/2017/02/16/1
- newly created thread may run with signals blocked
< sergei> there seems to be a race condition in pthread_create.c between lines 134 and 298
< sergei> if line 298 is executed before 134 (assuming syscall returned 0), startlock will be overwritten with zero, the condition will be evaluated to false and __restore_sigs will not be executed
< sergei> the newly created thread will run with all signals blocked
< sergei> i have a patch that fixes the issue for me: https://pastebin.com/T5QSd0C9
- missed underflow in fma
http://www.openwall.com/lists/musl/2017/03/19/6
new fma, depends on a_clz_64
http://www.openwall.com/lists/musl/2017/04/23/10
Pending due to need for additional analysis to determine exactly
what/where the bug is:
- mips64 utime issue?
"tar binary can't fix the modification/access times on any extracted symbolic links,"
http://www.openwall.com/lists/musl/2017/07/06/1
Pending due to open question about desired behavior:
- getservbyport(_r) should not report numeric ports
http://www.openwall.com/lists/musl/2017/02/06/5
- mmap should not return EPERM when it means ENOMEM
http://www.openwall.com/lists/musl/2017/01/12/1
- GLOB_PERIOD is inconsistent with glibc
http://www.openwall.com/lists/musl/2017/01/12/5
- ldso ctor dependency ordering and recursive dlopen fix
http://www.openwall.com/lists/musl/2017/01/03/6
Pending due to dependency of fix on larger change:
- use-after-free in __unlock of pthread struct
http://www.openwall.com/lists/musl/2017/06/01/7
Pending due to need to minor mechanical review:
- fix syscall number differences compared to linux uapi
http://www.openwall.com/lists/musl/2017/02/18/1
Pending due to missing patch:
- align arm hwcap.h with glibc (nsz)
Punting til later due to lack of serious/any outward symptoms and lack
of any practical way to fix:
- scanf, wrong types in va_arg
