* Fix tst-setcontext9 for optimized small stacks.Carlos O'Donell2018-09-202-9/+44
| | | | | | | | | | | | | | | | | | | If the compiler reduces the stack usage in function f1 before calling into function f2, then when we swapcontext back to f1 and continue execution we may overwrite registers that were spilled to the stack while f2 was executing. Later when we return to f2 the corrupt registers will be reloaded from the stack and the test will crash. This was most commonly observed on i686 with __x86.get_pc_thunk.dx and needing to save and restore $edx. Overall i686 has few registers and the spilling to the stack is bound to happen, therefore the solution to making this test robust is to split function f1 into two parts f1a and f1b, and allocate f1b it's own stack such that subsequent execution does not overwrite the stack in use by function f2. Tested on i686 and x86_64. Signed-off-by: Carlos O'Donell <carlos@redhat.com> (cherry picked from commit 791b350dc725545e3f9b5db0f97ebdbc60c9735f)

* Fix segfault in maybe_script_execute.Stefan Liebler2018-09-102-1/+6
| | | | | | | | | | | | | | | | | | | If glibc is built with gcc 8 and -march=z900, the testcase posix/tst-spawn4-compat crashes with a segfault. In function maybe_script_execute, the new_argv array is dynamically initialized on stack with (argc + 1) elements. The function wants to add _PATH_BSHELL as the first argument and writes out of bounds of new_argv. There is an off-by-one because maybe_script_execute fails to count the terminating NULL when sizing new_argv. ChangeLog: * sysdeps/unix/sysv/linux/spawni.c (maybe_script_execute): Increment size of new_argv by one. (cherry picked from commit 28669f86f6780a18daca264f32d66b1428c9c6f1)

* Keep expected behaviour for [a-z] and [A-z] (Bug 23393).Carlos O'Donell2018-07-255-1008/+1065
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 9479b6d5e08eacce06c6ab60abc9b2f4eb8b71e4 we updated all of the collation data to harmonize with the new version of ISO 14651 which is derived from Unicode 9.0.0. This collation update brought with it some changes to locales which were not desirable by some users, in particular it altered the meaning of the locale-dependent-range regular expression, namely [a-z] and [A-Z], and for en_US it caused uppercase letters to be matched by [a-z] for the first time. The matching of uppercase letters by [a-z] is something which is already known to users of other locales which have this property, but this change could cause significant problems to en_US and other similar locales that had never had this change before. Whether this behaviour is desirable or not is contentious and GNU Awk has this to say on the topic: https://www.gnu.org/software/gawk/manual/html_node/Ranges-and-Locales.html While the POSIX standard also has this further to say: "RE Bracket Expression": http://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xbd_chap09.html "The current standard leaves unspecified the behavior of a range expression outside the POSIX locale. ... As noted above, efforts were made to resolve the differences, but no solution has been found that would be specific enough to allow for portable software while not invalidating existing implementations." In glibc we implement the requirement of ISO POSIX-2:1993 and use collation element order (CEO) to construct the range expression, the API internally is __collseq_table_lookup(). The fact that we use CEO and also have 4-level weights on each collation rule means that we can in practice reorder the collation rules in iso14651_t1_common (the new data) to provide consistent range expression resolution *and* the weights should maintain the expected total order. Therefore this patch does three things: * Reorder the collation rules for the LATIN script in iso14651_t1_common to deinterlace uppercase and lowercase letters in the collation element orders. * Adds new test data en_US.UTF-8.in for sort-test.sh which exercises strcoll* and strxfrm* and ensures the ISO 14651 collation remains. * Add back tests to tst-fnmatch.input and tst-regexloc.c which exercise that [a-z] does not match A or Z. The reordering of the ISO 14651 data is done in an entirely mechanical fashion using the following program attached to the bug: https://sourceware.org/bugzilla/show_bug.cgi?id=23393#c28 It is up for discussion if the iso14651_t1_common data should be refined further to have 3 very tight collation element ranges that include only a-z, A-Z, and 0-9, which would implement the solution sought after in: https://sourceware.org/bugzilla/show_bug.cgi?id=23393#c12 and implemented here: https://www.sourceware.org/ml/libc-alpha/2018-07/msg00854.html No regressions on x86_64. Verified that removal of the iso14651_t1_common change causes tst-fnmatch to regress with: 422: fnmatch ("[a-z]", "A", 0) = 0 (FAIL, expected FNM_NOMATCH) *** ... 425: fnmatch ("[A-Z]", "z", 0) = 0 (FAIL, expected FNM_NOMATCH) ***
