Package: src:linux Version: 5.10.162-1 Severity: normal X-Debbugs-Cc: pk...@debian.org, elb...@debian.org, dipak.zo...@ibm.com
Dear Maintainer, What led up to the situation? * Processes does not proceed further, when there is a pending TIF_NOTIFY_SIGNAL signal. The problem is further described in the cover letter: https://lists.debian.org/debian-s390/2023/02/msg00019.html There are other relevant debian bugs #1030545, #1030510, which seems likely because of this issue. What exactly did you do (or not do) that was effective (or ineffective) ? * kernel upgrade to 5.10.0.21-s390x * commit 788d0824269b ("io_uring: import 5.15-stable io_uring") * commit 75309018a24d ("s390: add support for TIF_NOTIFY_SIGNAL") what was the outcome of this action? * Debian build machines started reporting test failures for multiple packages/ The processes would wait forever in do_signal. The following patch fixes this issue: https://lists.debian.org/debian-s390/2023/02/msg00019.html The patch fixes the problem introduced in commit 75309018a24d ("s390: add support for TIF_NOTIFY_SIGNAL") Would request to apply this to the bullseye kernel stable release. -- Package-specific info: ** Version: Linux version 5.10.0-21-s390x (debian-kernel@lists.debian.org) (gcc-10 (Debian 10.2.1-6) 10.2.1 20210110, GNU ld (GNU Binutils for Debian) 2.35.2) #1 SMP Debian 5.10.162-1 (2023-01-21) ** Command line: none ** Not tainted ** Kernel log: none ** Model information none ** Loaded modules: s390_trng rng_core prng ctr xts cbc ecb aes_generic libaes aes_s390 des_s390 libdes sha512_s390 sha256_s390 sha1_s390 sha_common qeth_l2 vmur qeth ccwgroup fuse configfs ip_tables x_tables autofs4 ext4 crc16 mbcache jbd2 crc32c_generic zfcp scsi_transport_fc scsi_mod dasd_eckd_mod dasd_mod ** PCI devices: ** USB devices: not available -- System Information: Debian Release: 11.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: s390x Kernel: Linux 5.10.0-21-s390x (SMP w/2 CPU threads) Locale: LANG=C, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages linux-image-5.10.0-21-s390x depends on: ii initramfs-tools [linux-initramfs-tool] 0.140 ii kmod 28-1 ii linux-base 4.6 Versions of packages linux-image-5.10.0-21-s390x recommends: ii apparmor 2.13.6-10 ii firmware-linux-free 20200122-1 Versions of packages linux-image-5.10.0-21-s390x suggests: pn debian-kernel-handbook <none> pn linux-doc-5.10 <none> ii s390-tools 2.15.1-2 Versions of packages linux-image-5.10.0-21-s390x is related to: pn firmware-amd-graphics <none> pn firmware-atheros <none> pn firmware-bnx2 <none> pn firmware-bnx2x <none> pn firmware-brcm80211 <none> pn firmware-cavium <none> pn firmware-intel-sound <none> pn firmware-intelwimax <none> pn firmware-ipw2x00 <none> pn firmware-ivtv <none> pn firmware-iwlwifi <none> pn firmware-libertas <none> pn firmware-linux-nonfree <none> pn firmware-misc-nonfree <none> pn firmware-myricom <none> pn firmware-netxen <none> pn firmware-qlogic <none> pn firmware-realtek <none> pn firmware-samsung <none> pn firmware-siano <none> pn firmware-ti-connectivity <none> pn xen-hypervisor <none> -- no debconf information
