socket: Use may_alias on sockaddr structs (bug 19622)

2024-05-18T07:33:19Z

This supports common coding patterns. The GCC C front end before version 7 rejects the may_alias attribute on a struct definition if it was not present in a previous forward declaration, so this attribute can only be conditionally applied. This implements the spirit of the change in Austin Group issue 1641. Suggested-by: Marek Polacek Suggested-by: Jakub Jelinek Reviewed-by: Sam James Reviewed-by: Carlos O'Donell

Always define __USE_TIME_BITS64 when 64 bit time_t is used

2024-04-02T18:28:36Z

It was raised on libc-help [1] that some Linux kernel interfaces expect the libc to define __USE_TIME_BITS64 to indicate the time_t size for the kABI. Different than defined by the initial y2038 design document [2], the __USE_TIME_BITS64 is only defined for ABIs that support more than one time_t size (by defining the _TIME_BITS for each module). The 64 bit time_t redirects are now enabled using a different internal define (__USE_TIME64_REDIRECTS). There is no expected change in semantic or code generation. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, and arm-linux-gnueabi [1] https://sourceware.org/pipermail/libc-help/2024-January/006557.html [2] https://sourceware.org/glibc/wiki/Y2038ProofnessDesign Reviewed-by: DJ Delorie

socket: Improve fortify with clang

It improve fortify checks recv, recvfrom, poll, and ppoll. The compile and runtime hecks have similar coverage as with GCC. Checked on aarch64, armhf, x86_64, and i686. Reviewed-by: Carlos O'Donell Tested-by: Carlos O'Donell

Exclude routines from fortification

2023-07-05T14:59:48Z

Since the _FORTIFY_SOURCE feature uses some routines of Glibc, they need to be excluded from the fortification. On top of that: - some tests explicitly verify that some level of fortification works appropriately, we therefore shouldn't modify the level set for them. - some objects need to be build with optimization disabled, which prevents _FORTIFY_SOURCE to be used for them. Assembler files that implement architecture specific versions of the fortified routines were not excluded from _FORTIFY_SOURCE as there is no C header included that would impact their behavior.

Fix all the remaining misspellings -- BZ 25337

socket: Reformat Makefile.

2023-05-16T11:19:31Z

Reflow Makefile. Sort using scripts/sort-makefile-lines.py. Code generation is changed as routines are linked in sorted order as expected. No regressions on x86_64 and i686.

socket: Fix tst-cmsghdr-skeleton.c use of cmsg_len

2023-05-01T13:05:09Z

cmsg_len is supposed to be socklen_t according to standards, but it was made size_t on Linux, see BZ 16919. For ports that have it socklen_t, SIZE_MAX is too large. We can however explicitly cast it to the type of cmsg_len so it will fit according to that type.
