2018-12-14fix issues in ethers.cWaldemar Brodkorb
Old version manages strings the regular way (i.e. counting on zero-ended sequences). In fact strings captured from the /etc/ethers file are '\n'-ended. So, for example, using strchr function could lead to buffer overflow. Reported-by: "Andrey V. Zhmurin" <zhmurin_a@mcst.ru
2018-12-14xtensa: add custom bits/poll.hMax Filippov
Definitions of POLLWRNORM, POLLWRBAND and POLLREMOVE in xtensa linux kernel are non-standard. Provide bits/poll.h with correct values for these constants. This fixes the following strace build errors: In file included from xlat/pollflags.h:4:0, from poll.c:34: ./static_assert.h:40:24: error: static assertion failed: "POLLWRBAND != 0x0100" # define static_assert _Static_assert ^ xlat/pollflags.h:75:1: note: in expansion of macro ‘static_assert’ static_assert((POLLWRBAND) == (0x0100), "POLLWRBAND != 0x0100"); ^~~~~~~~~~~~~ ./static_assert.h:40:24: error: static assertion failed: "POLLREMOVE != 0x0800" # define static_assert _Static_assert ^ xlat/pollflags.h:117:1: note: in expansion of macro ‘static_assert’ static_assert((POLLREMOVE) == (0x0800), "POLLREMOVE != 0x0800"); ^~~~~~~~~~~~~ Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2018-12-14several patches for uclibc nghan_mao@c-sky.com
I've got several patches to fix ltp/openmp/uclibc-ng-test testcase fail on c-sky. - fix a ltp testcase. - fix the problem that pthread creat will fail when libomp is linked before libc, the variable pagesize is not init. - fix tst-cancel4 and tst-cancel16. tst-cancelx4 and tst-cancelx16 still fail with this patch applied, cleanup handler is not called for open/creat/fcntl, seems some thing wrong with unwind, I haven't check the rootcause yet.

2018-11-27statfs.h: sync generic header with glibcWaldemar Brodkorb
Fix issues with aarch64 and df with mismatching header between kernel and libc.
2018-11-23Defined INLINE_SYSCALL_NOERR_NCS in mips/bits/syscalls.hVolodymyr Boyko
On Linux/MIPS (O32 ABI) for system call we have two result registers - v0 and a3. v0 contains actual syscall result on success or error number on fail, a3 set to 0/1 for indicating syscall success/fail. (if a3 == 1, v0 contains errno). Now as we can see from definition of handle_sys (arch/mips/kernel/scall32-o32.S), handler treats returned by syscall function (let's call "original") values in range [-EMAXERRNO; 0[ as -errno, a3 is set to 1 and final returned (to userspace) value is (-original). INLINE_SYSCALL_NOERR_NCS defined in mips/bits/syscalls.h will handle this behaviour. Signed-off-by: Volodymyr Boyko <boyko.cxx@gmail.com>

2018-10-27ARC: Accommodate TLS fix in BinutilsEvgeniy Didin
[1] fixes clash of TLS variables on ARC and since LD now calculates relocations a bit different now we need to update dynamic loader as well otherwise relocs will be calculated improperly. Note this is an ABI change and should go in-line with corresponding ARC tools. That said either arc-2018.09 (to be released in few weeks) or the next version of upstream Binutils (2.32) are required for normal TLS work on ARC. Testcase: ----------------------------------8<------------------------------- #include <stdio.h> int foo3(void); int foo1(void); #ifdef _SHARED int foo1(){ static __thread int val3=1; val3 += 2; return val3; } #elif _SHARED2 int foo3(){ static __thread int val2=0; val2 += 2; return val2; } #else int main(){ printf("foo1 = %d \n", foo1()); printf("foo3 = %d \n", foo3()); return 0; } #endif --------------------------------->8--------------------------------------- The result shoud be: ----8<---- foo1 = 3 foo3 = 2 ---->8---- Commands to build artefacts: ----------------------------------------8<------------------------------- arc-linux-gcc -fPIE -ffunction-sections -fdata-sections -pthread -Os \ -fPIC -o testtls.o -D_SHARED -c tst.c arc-linux-gcc -fPIE -ffunction-sections -fdata-sections -pthread -Os \ -fPIC -o testtls2.o -D_SHARED2 -c tst.c arc-linux-gcc -shared -o libtesttls.so testtls.o testtls2.o -lm -Os arc-linux-gcc tst.c -o tst.out -L./ -ltesttls -Os -fPIE --------------------------------->8--------------------------------------- Add path to libtesttls.so file to LD_LIBRARY_PATH before runnig tst.out application.

2018-08-10Fix htab_delete loop counterChristophe Lyon
dlclose can crash or stuck the system: When calling dlclose() then system can crash or freeze, because htab_delete() in ldso/ldso/fdpic/dl-inlines.h uses size_t for i which is a typedef to unsigned int. We exit the loop on negative value of i which can never occur since i is an unsigned int. This leads to random free of various pointers that kill the system. * ldso/include/inline-hashtab.h (htab_delete): Change type of 'i' to int.

2018-08-10nptl: Clear TLS area for static binaries.Christophe Lyon
busybox init checks it has pid 1, but getpid() returns another value when building busybox statically. This is because the corresponding area is not cleared when allocated (it is allocated with MAP_UNINITIALIZED, whose behavior depends on the Linux kernel's CONFIG_MMAP_ALLOW_UNINITIALIZED).
