The main patch is 2/2, which fixes some fortified headers to match feature macros with their corresponding main headers, without which functions would fail to get fortified. Patch 1/2 is a restructuring of the tests so that it is easier to add different configurations to _FORTIFY_SOURCE tests at various levels. Tested on x86_64 to confirm that there were no new regressions due to this and that the new tests also run clean. Changes from v1: - Rebased against latest trunk so that the patches actually apply. - Renamed files so that the diffs are easier to compare and also make a bit more sense. Changes from v2: - Renamed tst-chk-0.c to tst-fortify.c and autogenerate all tests and include it. - Set all the flags we can as -D in CFLAGS and autogenerate test cases if needed. - Fix other review comments. Changes from v3: - Fixed typo (chk-gen-locals -> chk-gen-locales) Siddhesh Poyarekar (2): debug: Autogenerate _FORTIFY_SOURCE tests debug: Synchronize feature guards in fortified functions [BZ #28746] debug/Makefile | 115 ++++++++++++++++++---------- debug/tst-chk2.c | 2 - debug/tst-chk3.c | 2 - debug/tst-chk4.cc | 1 - debug/tst-chk5.cc | 2 - debug/tst-chk6.cc | 2 - debug/tst-chk7.c | 2 - debug/tst-chk8.cc | 2 - debug/tst-fortify-c-default-1.c | 3 + debug/tst-fortify-c-default-2.c | 3 + debug/tst-fortify-c-default-3.c | 3 + debug/tst-fortify-c-lfs-1.c | 3 + debug/tst-fortify-c-lfs-2.c | 3 + debug/tst-fortify-c-lfs-3.c | 3 + debug/tst-fortify-c-nongnu-1.c | 3 + debug/tst-fortify-c-nongnu-2.c | 3 + debug/tst-fortify-c-nongnu-3.c | 3 + debug/tst-fortify-cc-default-1.cc | 3 + debug/tst-fortify-cc-default-2.cc | 3 + debug/tst-fortify-cc-default-3.cc | 3 + debug/tst-fortify-cc-lfs-1.cc | 3 + debug/tst-fortify-cc-lfs-2.cc | 3 + debug/tst-fortify-cc-lfs-3.cc | 3 + debug/tst-fortify-cc-nongnu-1.cc | 3 + debug/tst-fortify-cc-nongnu-2.cc | 3 + debug/tst-fortify-cc-nongnu-3.cc | 3 + debug/{tst-chk1.c => tst-fortify.c} | 49 ++++++++++-- debug/tst-lfschk1.c | 2 - debug/tst-lfschk2.c | 2 - debug/tst-lfschk3.c | 2 - debug/tst-lfschk4.cc | 2 - debug/tst-lfschk5.cc | 2 - debug/tst-lfschk6.cc | 2 - posix/bits/unistd.h | 2 +- string/bits/string_fortified.h | 8 +- support/xsignal.h | 2 + wcsmbs/bits/wchar2.h | 2 +- 37 files changed, 177 insertions(+), 80 deletions(-) delete mode 100644 debug/tst-chk2.c delete mode 100644 debug/tst-chk3.c delete mode 100644 debug/tst-chk4.cc delete mode 100644 debug/tst-chk5.cc delete mode 100644 debug/tst-chk6.cc delete mode 100644 debug/tst-chk7.c delete mode 100644 debug/tst-chk8.cc create mode 100644 debug/tst-fortify-c-default-1.c create mode 100644 debug/tst-fortify-c-default-2.c create mode 100644 debug/tst-fortify-c-default-3.c create mode 100644 debug/tst-fortify-c-lfs-1.c create mode 100644 debug/tst-fortify-c-lfs-2.c create mode 100644 debug/tst-fortify-c-lfs-3.c create mode 100644 debug/tst-fortify-c-nongnu-1.c create mode 100644 debug/tst-fortify-c-nongnu-2.c create mode 100644 debug/tst-fortify-c-nongnu-3.c create mode 100644 debug/tst-fortify-cc-default-1.cc create mode 100644 debug/tst-fortify-cc-default-2.cc create mode 100644 debug/tst-fortify-cc-default-3.cc create mode 100644 debug/tst-fortify-cc-lfs-1.cc create mode 100644 debug/tst-fortify-cc-lfs-2.cc create mode 100644 debug/tst-fortify-cc-lfs-3.cc create mode 100644 debug/tst-fortify-cc-nongnu-1.cc create mode 100644 debug/tst-fortify-cc-nongnu-2.cc create mode 100644 debug/tst-fortify-cc-nongnu-3.cc rename debug/{tst-chk1.c => tst-fortify.c} (97%) delete mode 100644 debug/tst-lfschk1.c delete mode 100644 debug/tst-lfschk2.c delete mode 100644 debug/tst-lfschk3.c delete mode 100644 debug/tst-lfschk4.cc delete mode 100644 debug/tst-lfschk5.cc delete mode 100644 debug/tst-lfschk6.cc
