This leads to -a crash in FlushAllOutput() after x11proto's commit -2c94cdb453bc641246cc8b9a876da9799bee1ce7. - -The problem did not manifest before because both the XFD_SIZE and the maximum -number of clients were set to 256. As the connectionTranslation table was -initalized for the 256 clients to 0, the test on the index not being 0 was -aborting before dereferencing the client #0. - -As of commit 2c94cdb453bc641246cc8b9a876da9799bee1ce7 in x11proto, the XFD_SIZE -got bumped to 512. This lead the OutputPending fd_set to have any fd above 256 -to be uninitialized which in turns lead to reading an index after the end of -the ConnectionTranslation table. This index would then be used to find the -client corresponding to the fd marked as pending writes and would also result -to an out-of-bound access which would usually be the fatal one. - -Fix this by zeroing the clientsWritable fd_set at the beginning of -WaitForSomething(). In this case, the bottom part of the loop, which would -indirectly call FlushAllOutput, will not do any work but the next call to -select will result in the execution of the right codepath. This is exactly what -we want because we need to know the writable clients before handling them. In -the end, it also makes sure that the fds above MaxClient are initialized, -preventing the crash in FlushAllOutput(). - -Thanks to everyone involved in tracking this one down! - -Reported-by: Karol Herbst -Reported-by: Tobias Klausmann -Signed-off-by: Martin Peres -Tested-by: Martin Peres -Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91316 -Cc: Ilia Mirkin -Cc: Martin Peres -Cc: Olivier Fourdan -Cc: Alan Coopersmith ---- - os/WaitFor.c | 1 + - 1 file changed, 1 insertion(+) - -diff --git a/os/WaitFor.c b/os/WaitFor.c -index 431f1a6..993c14e 100644 ---- a/os/WaitFor.c -+++ b/os/WaitFor.c -@@ -158,6 +158,7 @@ WaitForSomething(int *pClientsReady) - Bool someReady = FALSE; - - FD_ZERO(&clientsReadable); -+ FD_ZERO(&clientsWritable); - - if (nready) - SmartScheduleStopTimer(); --- -2.4.5 - diff --git a/libre/xorg-server/PKGBUILD b/libre/xorg-server/PKGBUILD index 16735acd3..8dad3bd73 100644 --- a/libre/xorg-server/PKGBUILD +++ b/libre/xorg-server/PKGBUILD @@ -5,7 +5,7 @@ pkgbase=xorg-server pkgname=('xorg-server') -pkgver=1.17.3 +pkgver=1.17.4 pkgrel=1.parabola1 arch=('i686' 'x86_64' 'armv7h') license=('custom') @@ -22,19 +22,17 @@ source=(${url}/releases/individual/xserver/${pkgbase}-${pkgver}.tar.bz2{,.sig} xvfb-run.1 0001-dix-Add-unaccelerated-valuators-to-the-ValuatorMask.patch 0002-dix-hook-up-the-unaccelerated-valuator-masks.patch - 0001-systemd-logind-do-not-rely-on-directed-signals.patch - 0001-os-make-sure-the-clientsWritable-fd_set-is-initializ.patch) + 0001-systemd-logind-do-not-rely-on-directed-signals.patch) validpgpkeys=('7B27A3F1A6E18CD9588B4AE8310180050905E40C' 'C383B778255613DFDB409D91DB221A6900000011' 'DD38563A8A8224537D1F90E45B8A2D50A0ECD0D3') -sha256sums=('89b5c6b7e7ec4731645283d2178f607825b75a470e76b3ad3cb1c1dbd2456b73' +sha256sums=('0c4b45c116a812a996eb432d8508cf26c2ec8c3916ff2a50781796882f8d6457' 'SKIP' 'ff0156309470fc1d378fd2e104338020a884295e285972cc88e250e031cc35b9' '2460adccd3362fefd4cdc5f1c70f332d7b578091fb9167bf88b5f91265bbd776' '3dc795002b8763a7d29db94f0af200131da9ce5ffc233bfd8916060f83a8fad7' '416a1422eed71efcebb1d893de74e7f27e408323a56c4df003db37f5673b3f96' - '3d7edab3a54d647e7d924b29d29f91b50212f308fcb1853a5aacd3181f58276c' - 'efc05c06af2bfdf588ef7a60b44c1d180fb353b1bffdfdf96415d63690b6e394') + '3d7edab3a54d647e7d924b29d29f91b50212f308fcb1853a5aacd3181f58276c') prepare() { cd "${pkgbase}-${pkgver}" @@ -45,9 +43,6 @@ prepare() { # fix VT switching with kdbus; from upstream patch -Np1 -i ../0001-systemd-logind-do-not-rely-on-directed-signals.patch - # fix FS#45009, merged upstream - patch -Np1 -i ../0001-os-make-sure-the-clientsWritable-fd_set-is-initializ.patch - # fix os name: #Build Operating System = OSNAME="--kernel-name --kernel-release --machine" OSVENDOR="" #Current Operating System = --kernel-name --nodename --kernel-release --kernel-version --machine -- cgit v1.2.3
