* x86: Use 64MB as nt-store threshold if no cacheinfo [BZ #30429]Noah Goldstein2023-05-271-1/+9
| | | | | | | | | | | | If `non_temporal_threshold` is below `minimum_non_temporal_threshold`, it almost certainly means we failed to read the systems cache info. In this case, rather than defaulting the minimum correct value, we should default to a value that gets at least reasonable performance. 64MB is chosen conservatively to be at the very high end. This should never cause non-temporal stores when, if we had read cache info, we wouldn't have otherwise. Reviewed-by: Florian Weimer <fweimer@redhat.com>

* Add MFD_NOEXEC_SEAL, MFD_EXEC from Linux 6.3 to bits/mman-shared.hJoseph Myers2023-05-261-0/+4
| | | | | | | | | Linux 6.3 adds new constants MFD_NOEXEC_SEAL and MFD_EXEC. Add these to bits/mman-shared.h (conditional on MFD_NOEXEC_SEAL not already being defined, similar to the existing conditional on the older MFD_* macros). Tested for x86_64.

| | | | | | | Linux 6.3 adds a new constant IP_LOCAL_PORT_RANGE. Add it to the corresponding bits/in.h in glibc. Tested for x86_64.
* Add AT_RSEQ_* from Linux 6.3 to elf.hJoseph Myers2023-05-261-0/+3
| | | | | | | | | | | Linux 6.3 adds constants AT_RSEQ_FEATURE_SIZE and AT_RSEQ_ALIGN; add them to glibc's elf.h. (Recall that, although elf.h is a system-independent header, so far we've put AT_* constants there even if Linux-specific, as discussed in bug 15794. So rather than making any attempt to fix that issue, the new constants are just added there alongside the existing ones.) Tested for x86_64.

| | | | | | | | | | | | _dl_debug_vdprintf is a bare-bones printf implementation; currently printing a signed integer (using "%d" format specifier) behaves incorrectly when the number is negative, as it just prints the corresponding unsigned integer, preceeded by a minus sign.

* elf: Add test for locating libraries in root dir (bug 30435)Qixing ksyx Xue2023-05-255-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When dlopen is being called, efforts have been made to improve future lookup performance. This includes marking a search path as non-existent using `stat`. However, if the root directory is given as a search path, there exists a bug which erroneously marks it as non-existing. The bug is reproduced under the following sequence: 1. dlopen is called to open a shared library, with at least: 1) a dependency 'A.so' not directly under the '/' directory (e.g. /lib/A.so), and 2) another dependency 'B.so' resides in '/'. 2. for this bug to reproduce, 'A.so' should be searched *before* 'B.so'. 3. it first tries to find 'A.so' in /, (e.g. /A.so): - this will (obviously) fail, - since it's the first time we have seen the '/' directory, its 'status' is 'unknown'. 4. `buf[buflen - namelen - 1] = '\0'` is executed: - it intends to remove the leaf and its final slash, - because of the speciality of '/', its buflen == namelen + 1, - it erroneously clears the entire buffer. 6. it then calls 'stat' with the empty buffer: - which will result in an error. 7. so it marks '/' as 'nonexisting', future lookups will not consider this path. 8. while /B.so *does* exist, failure to look it up in the '/' directory leads to a 'cannot open shared object file' error. This patch fixes the bug by preventing 'buflen', an index to put '\0', from being set to 0, so that the root '/' is always kept. Relative search paths are always considered as 'existing' so this wont be affected.

* S390: Use compile-only instead of also link-tests in configure.Stefan Liebler2023-05-222-177/+109
| | | | | | | | | | | | | | | | | Some of the s390-specific configure checks are using compile and link configure tests. Now use only compile tests as the link tests fails when e.g. bootstrapping a cross-toolchain due to missing crt-files/libc.so. This is achieved by using AC_COMPILE_IFELSE in configure.ac file. This is observable e.g. when using buildroot which builds glibc only once or the build-many-glibcs.py script. Note that the latter one is building glibc twice in the compilers-step (configure-checks fails) and in the glibcs-step (configure-checks succeed). Note, that the s390 specific configure tests for static PIE have to link an executable to test binutils support. Thus we can't fix those tests.
