* Fix string/tst-xbzero-opt if build with gcc head.Stefan Liebler2018-07-262-0/+20

* 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) ***

* x86-64/CET: Extend ucontext_t to save shadow stackH.J. Lu2018-07-259-1/+421
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a field to ucontext_t to save shadow stack: 1. getcontext and swapcontext are updated to save the caller's shadow stack pointer and return addresses. 2. setcontext and swapcontext are updated to restore shadow stack and jump to new context directly. 3. makecontext is updated to allocate a new shadow stack and set the caller's return address to __start_context. Since makecontext allocates a new shadow stack when making a new context and kernel allocates a new shadow stack for clone/fork/vfork syscalls, we track the current shadow stack base. In setcontext and swapcontext, if the target shadow stack base is the same as the current shadow stack base, we unwind the shadow stack. Otherwise it is a stack switch and we look for a restore token. We enable shadow stack at run-time only if program and all used shared objects, including dlopened ones, are shadow stack enabled, which means that they must be compiled with GCC 8 or above and glibc 2.28 or above. We need to save and restore shadow stack only if shadow stack is enabled. When caller of getcontext, setcontext, swapcontext and makecontext is compiled with smaller ucontext_t, shadow stack won't be enabled at run-time. We check if shadow stack is enabled before accessing the extended field in ucontext_t.
