Release announcements
by Ata, John (US) 03 Dec '20

03 Dec '20

Hi, I seem to recall in the past that new uclibc-ng releases would be announced in this group. The last two release announcements (1.0.35 and 1.0.36) do not appear in my feed. Perhaps my mail server discarded them but I wonder if we are still announcing them to the group or are we counting on people manually checking the website?

[PATCH] hasmntopt: better option matching
by yann＠sionneau.net 19 Oct '20

19 Oct '20

From: Yann Sionneau <yann(a)sionneau.net> Previous implementation was respecting the man page description of what the function should do. Also the function does not seem to be defined by POSIX. But... to be really useful the function needs to handle option matching and not just substring matching. This is copy pasted from glibc.

Hi Waldemar, sorry to be impatient, but would you mind to create release to help distros not backporting all the fixes? Kind regards, Petr

[PATCH 0/1] Fix missing Feature Test Macro check in common stat.h
by Yann Sionneau 18 Sep '20

18 Sep '20

This is a touchy change since it touches a common header. This needs a thorough review in order not to break something. But for the record glibc only tests for __USE_XOPEN2K8 and musl does not test for anything at all and directly uses timespec fields. glibc: https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/ge… musl: https://git.musl-libc.org/cgit/musl/tree/arch/aarch64/bits/stat.h Yann Sionneau (1): Fix memory corruption due to struct stat field libc/sysdeps/linux/common-generic/bits/stat.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) -- 2.17.1
