* elf: Fix runtime linker auditing on aarch64 (BZ #26643)Ben Woodard2022-02-0116-41/+779
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rtld audit support show two problems on aarch64: 1. _dl_runtime_resolve does not preserve x8, the indirect result location register, which might generate wrong result calls depending of the function signature. 2. The NEON Q registers pushed onto the stack by _dl_runtime_resolve were twice the size of D registers extracted from the stack frame by _dl_runtime_profile. While 2. might result in wrong information passed on the PLT tracing, 1. generates wrong runtime behaviour. The aarch64 rtld audit support is changed to: * Both La_aarch64_regs and La_aarch64_retval are expanded to include both x8 and the full sized NEON V registers, as defined by the ABI. * dl_runtime_profile needed to extract registers saved by _dl_runtime_resolve and put them into the new correctly sized La_aarch64_regs structure. * The LAV_CURRENT check is change to only accept new audit modules to avoid the undefined behavior of not save/restore x8. * Different than other architectures, audit modules older than LAV_CURRENT are rejected (both La_aarch64_regs and La_aarch64_retval changed their layout and there are no requirements to support multiple audit interface with the inherent aarch64 issues). * A new field is also reserved on both La_aarch64_regs and La_aarch64_retval to support variant pcs symbols. Similar to x86, a new La_aarch64_vector type to represent the NEON register is added on the La_aarch64_regs (so each type can be accessed directly). Since LAV_CURRENT was already bumped to support bind-now, there is no need to increase it again. Checked on aarch64-linux-gnu.

* elf: Issue la_symbind for bind-now (BZ #23734)Adhemerval Zanella2022-02-0135-39/+1379
| | | | | | | | | | | | | | | | | | | | | | | The audit symbind callback is not called for binaries built with -Wl,-z,now or when LD_BIND_NOW=1 is used, nor the PLT tracking callbacks (plt_enter and plt_exit) since this would change the expected program semantics (where no PLT is expected) and would have performance implications (such as for BZ#15533). LAV_CURRENT is also bumped to indicate the audit ABI change (where la_symbind flags are set by the loader to indicate no possible PLT trace). To handle powerpc64 ELFv1 function descriptor, _dl_audit_symbind requires to know whether bind-now is used so the symbol value is updated to function text segment instead of the OPD (for lazy binding this is done by PPC64_LOAD_FUNCPTR on _dl_runtime_resolve).

* elf: Fix initial-exec TLS access on audit modules (BZ #28096)Adhemerval Zanella2022-02-018-6/+169
| | | | | | | | | | | | | | | | | For audit modules and dependencies with initial-exec TLS, we can not set the initial TLS image on default loader initialization because it would already be set by the audit setup. However, subsequent thread creation would need to follow the default behaviour. This patch fixes it by setting l_auditing link_map field not only for the audit modules, but also for all its dependencies. This is used on _dl_allocate_tls_init to avoid the static TLS initialization at load time. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu.

* localedata: Adjust C.UTF-8 to align with C/POSIX.Carlos O'Donell2022-02-013-13/+578
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have had one downstream report from Canonical [1] that an rrdtool test was broken by the differences in LC_TIME that we had in the non-builtin C locale (C.UTF-8). If one application has an issue there are going to be others, and so with this commit we review and fix all the issues that cause the builtin C locale to be different from C.UTF-8, which includes: * mon_decimal_point should be empty e.g. "" - Depends on mon_decimal_point_wc fix. * negative_sign should be empty e.g. "" * week should be aligned with the builtin C/POSIX locale * d_fmt corrected with escaped slashes e.g. "%m//%d//%y" * yesstr and nostr should be empty e.g. "" * country_ab2 and country_ab3 should be empty e.g. "" We bump LC_IDENTIFICATION version and adjust the date to indicate the change in the locale. A new tst-c-utf8-consistency test is added to ensure consistency between C/POSIX and C.UTF-8. Tested on x86_64 and i686 without regression.

* localedef: Fix handling of empty mon_decimal_point (Bug 28847)Carlos O'Donell2022-02-011-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling of mon_decimal_point is incorrect when it comes to handling the empty "" value. The existing parser in monetary_read() will correctly handle setting the non-wide-character value and the wide-character value e.g. STR_ELEM_WC(mon_decimal_point) if they are set in the locale definition. However, in monetary_finish() we have conflicting TEST_ELEM() which sets a default value (if the locale definition doesn't include one), and subsequent code which looks for mon_decimal_point to be NULL to issue a specific error message and set the defaults. The latter is unused because TEST_ELEM() always sets a default. The simplest solution is to remove the TEST_ELEM() check, and allow the existing check to look to see if mon_decimal_point is NULL and set an appropriate default. The final fix is to move the setting of mon_decimal_point_wc so it occurs only when mon_decimal_point is being set to a default, keeping both values consistent. There is no way to tell the difference between mon_decimal_point_wc having been set to the empty string and not having been defined at all, for that distinction we must use mon_decimal_point being NULL or "", and so we must logically set the default together with mon_decimal_point. Lastly, there are more fixes similar to this that could be made to ld-monetary.c, but we avoid that in order to fix just the code required for mon_decimal_point, which impacts the ability for C.UTF-8 to set mon_decimal_point to "", since without this fix we end up with an inconsistent setting of mon_decimal_point set to "", but mon_decimal_point_wc set to "." which is incorrect.

* Linux: Only generate 64 bit timestamps for 64 bit time_t recvmsg/recvmmsgAdhemerval Zanella2022-01-286-26/+330
| | | | | | | | | | | | | | | | | | | | | | | The timestamps created by __convert_scm_timestamps only make sense for 64 bit time_t programs, 32 bit time_t programs will ignore 64 bit time_t timestamps since SO_TIMESTAMP will be defined to old values (either by glibc or kernel headers). Worse, if the buffer is not suffice MSG_CTRUNC is set to indicate it (which breaks some programs [1]). This patch makes only 64 bit time_t recvmsg and recvmmsg to call __convert_scm_timestamps. Also, the assumption to called it is changed from __ASSUME_TIME64_SYSCALLS to __TIMESIZE != 64 since the setsockopt might be called by libraries built without __TIME_BITS=64. The MSG_CTRUNC is only set for the 64 bit symbols, it should happen only if 64 bit time_t programs run older kernels. Checked on x86_64-linux-gnu and i686-linux-gnu.

* posix: Add terminal control setting support for posix_spawnAdhemerval Zanella2022-01-2546-6/+354
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no proper way to set the controlling terminal through posix_spawn in race free manner [1]. This forces shell implementations to keep using fork+exec when launching background process groups, even when using posix_spawn yields better performance. This patch adds a new GNU extension so the creating process can configure the created process terminal group. This is done with a new flag, POSIX_SPAWN_TCSETPGROUP, along with two new attribute functions: posix_spawnattr_tcsetpgrp_np, and posix_spawnattr_tcgetpgrp_np. The function sets a new attribute, spawn-tcgroupfd, that references to the controlling terminal. The controlling terminal is set after the spawn-pgroup attribute, and uses the spawn-tcgroupfd along with current creating process group (so it is composable with POSIX_SPAWN_SETPGROUP). To create a process and set the controlling terminal, one can use the following sequence: posix_spawnattr_t attr; posix_spawnattr_init (&attr); posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP); posix_spawnattr_tcsetpgrp_np (&attr, tcfd); If the idea is also to create a new process groups: posix_spawnattr_t attr; posix_spawnattr_init (&attr); posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP | POSIX_SPAWN_SETPGROUP); posix_spawnattr_tcsetpgrp_np (&attr, tcfd); posix_spawnattr_setpgroup (&attr, 0); The controlling terminal file descriptor is ignored if the new flag is not set. This interface is slight different than the one provided by QNX [2], which only provides the POSIX_SPAWN_TCSETPGROUP flag. The QNX documentation does not specify how the controlling terminal is obtained nor how it iteracts with POSIX_SPAWN_SETPGROUP. Since a glibc implementation is library based, it is more straightforward and avoid requires additional file descriptor operations to request the caller to setup the controlling terminal file descriptor (and it also allows a bit less error handling by posix_spawn).
