| | | | | | | | | | | | | | | | For configurations with cross-compiling equal to 'maybe' or 'no', ldconfig will not run and thus the ld.so.cache will not be created on the container testroot.pristine. This lead to failures on both tst-glibc-hwcaps-prepend-cache and tst-ldconfig-ld_so_conf-update on environments where the same compiler can be used to build different ABIs (powerpc and x86 for instance). This patch addas a new test-container hook, ldconfig.run, that triggers a ldconfig execution prior the test execution. Checked on x86_64-linux-gnu and i686-linux-gnu.

* powerpc64: Workaround sigtramp vdso return callRaoni Fassina Firmino2021-01-281-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A not so recent kernel change[1] changed how the trampoline `__kernel_sigtramp_rt64` is used to call signal handlers. This was exposed on the test misc/tst-sigcontext-get_pc Before kernel 5.9, the kernel set LR to the trampoline address and jumped directly to the signal handler, and at the end the signal handler, as any other function, would `blr` to the address set. In other words, the trampoline was executed just at the end of the signal handler and the only thing it did was call sigreturn. But since kernel 5.9 the kernel set CTRL to the signal handler and calls to the trampoline code, the trampoline then `bctrl` to the address in CTRL, setting the LR to the next instruction in the middle of the trampoline, when the signal handler returns, the rest of the trampoline code executes the same code as before. Here is the full trampoline code as of kernel 5.11.0-rc5 for reference: V_FUNCTION_BEGIN(__kernel_sigtramp_rt64) .Lsigrt_start: bctrl /* call the handler */ addi r1, r1, __SIGNAL_FRAMESIZE li r0,__NR_rt_sigreturn sc .Lsigrt_end: V_FUNCTION_END(__kernel_sigtramp_rt64) This new behavior breaks how `backtrace()` uses to detect the trampoline frame to correctly reconstruct the stack frame when it is called from inside a signal handling. This workaround rely on the fact that the trampoline code is at very least two (maybe 3?) instructions in size (as it is in the 32 bits version, only on `li` and `sc`), so it is safe to check the return address be in the range __kernel_sigtramp_rt64 .. + 4.

* elf: Limit tst-prelink-cmp target archsMatheus Castanho2021-01-273-8/+51
| | | | | | | | | | | | | | elf/tst-prelink-cmp was initially added for x86 (commit fe534fe898) to validate the fix for Bug 19178, and later applied to all architectures that use GLOB_DAT relocations (commit 89569c8bb6). However, that bug only affected targets that handle GLOB_DAT relocations as ELF_TYPE_CLASS_EXTERN_PROTECTED_DATA, so the test should only apply to targets defining DL_EXTERN_PROTECTED_DATA, which gates the usage of the elf type class above. For all other targets not meeting that criteria, the test now returns with UNSUPPORTED status. Fixes the test on POWER10 processors, which started using R_PPC64_GLOB_DAT.

* gconv: Fix assertion failure in ISO-2022-JP-3 module (bug 27256)Florian Weimer2021-01-273-20/+178
| | | | | | | | | | | | | | | | | | The conversion loop to the internal encoding does not follow the interface contract that __GCONV_FULL_OUTPUT is only returned after the internal wchar_t buffer has been filled completely. This is enforced by the first of the two asserts in iconv/skeleton.c: /* We must run out of output buffer space in this rerun. */ assert (outbuf == outerr); assert (nstatus == __GCONV_FULL_OUTPUT); This commit solves this issue by queuing a second wide character which cannot be written immediately in the state variable, like other converters already do (e.g., BIG5-HKSCS or TSCII).
