* Reduce the statically linked startup code [BZ #23323]Florian Weimer2021-02-252-0/+2
| | | | | | | | | | | | | | | | | | | It turns out the startup code in csu/elf-init.c has a perfect pair of ROP gadgets (see Marco-Gisbert and Ripoll-Ripoll, "return-to-csu: A New Method to Bypass 64-bit Linux ASLR"). These functions are not needed in dynamically-linked binaries because DT_INIT/DT_INIT_ARRAY are already processed by the dynamic linker. However, the dynamic linker skipped the main program for some reason. For maximum backwards compatibility, this is not changed, and instead, the main map is consulted from __libc_start_main if the init function argument is a NULL pointer. For statically linked binaries, the old approach based on linker symbols is still used because there is nothing else available. A new symbol version __libc_start_main@@GLIBC_2.34 is introduced because new binaries running on an old libc would not run their ELF constructors, leading to difficult-to-debug issues.
* Update syscall lists for Linux 5.11.Joseph Myers2021-02-192-0/+2
| | | | | | | | Linux 5.11 has one new syscall, epoll_pwait2. Update syscall-names.list and regenerate the arch-syscall.h headers with build-many-glibcs.py update-syscalls. Tested with build-many-glibcs.py.
* linux: Set default kernel_stat.h to LFSAdhemerval Zanella2021-02-111-23/+0
| | | | | | | | | | | | | | The XSTAT_IS_XSTAT64 and STAT_IS_KERNEL_STAT flags are now set to 1 and STATFS_IS_STATFS64 is set to __STATFS_MATCHES_STATFS64. This makes the default ABI for newer ports to provide only LFS calls. A copy of non-LFS support is provided to 32-bit ABIS with non-LFS support (arm, csky, i386, m68k, nios2, s390, and sh). Is also allows to remove the 64-bit ports, which already uses the default values. This patch does not change the code generation. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* linux: Fix STATFS_IS_STATFS64 definitionAdhemerval Zanella2021-02-111-1/+1
| | | | | | | | | | | | | | | aarch64, arc, ia64, mips64, powerpc64, riscv32, riscv64, s390x, sparc64, and x86_64 defines STATFS_IS_STATFS64 to 0, but all of them alias statfs to statfs64 and the struct statfs has the same and layout of struct statfs64. The correct definition will be used on the [f]statfs[64] consolidation. This patch does not change code generation since the symbols are implemented using the auto-generation syscall for all the aforementioned ABIs. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* ldconfig/x86: Store ISA level in cache and aux cacheH.J. Lu2021-01-131-10/+12
| | | | | | | | | | | Store ISA level in the portion of the unused upper 32 bits of the hwcaps field in cache and the unused pad field in aux cache. ISA level is stored and checked only for shared objects in glibc-hwcaps subdirectories. The shared objects in the default directories aren't checked since there are no fallbacks for these shared objects. Tested on x86-64-v2, x86-64-v3 and x86-64-v4 machines with --disable-hardcoded-path-in-tests and --enable-hardcoded-path-in-tests.

I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* linux: Consolidate brk implementationAdhemerval Zanella2020-12-101-0/+3
| | | | | | | | | | | | | | | It removes all the arch-specific assembly implementation. The outliers are alpha, where its kernel ABI explict return -ENOMEM in case of failure; and i686, where it can't use "call *%gs:SYSINFO_OFFSET" during statup in static PIE. Also some ABIs exports an additional ___brk_addr symbol and to handle it an internal HAVE_INTERNAL_BRK_ADDR_SYMBOL is added. Checked on x86_64-linux-gnu, i686-linux-gnu, adn with builsd for the affected ABIs. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
* Remove tls.h inclusion from internal errno.hAdhemerval Zanella2020-11-131-0/+1
| | | | | | | | | | | | The tls.h inclusion is not really required and limits possible definition on more arch specific headers. This is a cleanup to allow inline functions on sysdep.h, more specifically on i386 and ia64 which requires to access some tls definitions its own. No semantic changes expected, checked with a build against all affected ABIs.

* Move vtimes to a compatibility symbolAdhemerval Zanella2020-10-191-1/+0
| | | | | | | | | | | | | | I couldn't pinpoint which standard has added it, but no other POSIX system supports it and/or no longer provide it. The 'struct vtimes' also has a lot of drawbacks due its limited internal type size. I couldn't also see find any project that actually uses this symbol, either in some dignostic way (such as sanitizer). So I think it should be safer to just move to compat symbol, instead of deprecated. The idea it to avoid new ports to export such broken interface (riscv32 for instance). Checked on x86_64-linux-gnu and i686-linux-gnu.

| | | | | | | | | | It was made deprecated on 2.31, so it moves to compat symbol after two releases. It was also removed from exported symbol for riscv32 (since ABI will be supported on for 2.33). Checked on x86_64-linux-gnu and i686-linux-gnu. Reviewed-by: Lukasz Majewski <lukma@denx.de>

* Allow memset local PLT reference for RISC-V.Alistair Francis2020-09-171-0/+1
| | | | | | | | | | | | | | | | This is similar to commit a26e2e9feab87d4f745c31411458b048742ac733 "Allow memset local PLT reference for powerpc soft-float.". GCC 10.1 results in the localplt test failing for RISC-V. From the original commit for power-pc: Since memset is documented as a function GCC may always implicitly generate calls to, it seems reasonable to allow that local PLT reference (just like those for libgcc functions that GCC implicitly generates calls to and that are also exported from libc.so), which this patch does.

* RISC-V: Use 64-bit time_t and off_t for RV32 and RV64Alistair Francis2020-08-274-0/+162
| | | | | | | | | | | | | | | | | | | | | | Using the original glibc headers under bits/ let's make small modifications to use 64-bit time_t and off_t for both RV32 and RV64. For the typesizes.h, here are justifications for the changes from the generic version (based on Arnd's very helpful feedback): - All the !__USE_FILE_OFFSET64 types (__off_t, __ino_t, __rlim_t, ...) are changed to match the 64-bit replacements. - __time_t is defined to 64 bit, but no __time64_t is added. This makes sense as we don't have the time64 support for other 32-bit architectures yet, and it will be easy to change when that happens. - __suseconds_t is 64-bit. This matches what we use the kernel ABI for the few drivers that are relying on 'struct timeval' input arguments in ioctl, as well as the adjtimex system call. It means that timeval has to be defined without the padding, unlike timespec, which needs padding. Reviewed-by: Maciej W. Rozycki <macro@wdc.com>
