Thus we are invoked as e.g. /sbin/installkernel 5.18.0 arch/x86/boot/bzImage System.map /boot The last two arguments would be passed as "initrds". Before , we would just quitely ignore /boot, because it doesn't pass the 'test -f' test, and possibly try to do something with System.map. 742561efbe938c45936f2e4f5d81b3ff6b352882 tightened the check, so we now throw an error. It seems that the correct thing is to ignore those two arguments, because our plugin syntax has no notion of System.map. And the installation directory we can figure out ourselves better. Effectively, this makes things behave like before, but less by accident. Fixes #23490.

Replaces #23555. The problem started with cdf370626f08ed509a5dde9d5618eed29d625032 and 90b1ec03b2ce939f589239133a32f4429f2ad6a6 which together started printing the wall message in more cases. The motivation for those change was reasonable, but this clearly causes problems described in #23520: users are getting unexpected wall messages. Xterm, urxvt, (anything using libutempter?), and tmux (in some configurations), register local pty sessions in utmp. So let's try to suppress the message for local pseudo-terminal logins. This patch based on #23538, but instead of filtering just on /dev/pts, it uses the .ut_addr_v6 to only filter out local entries.

Replies to such local messages need to set a proper ifindex in any case, as the supplied source-address would otherwise be ignored in manager_ipv4_send() (CMSG generation is skipped due to ifindex > 0 check). Note that this change only forces `ifindex` to loopback if it was actually normalized to `0` before (due to a loopback detection) in order to keep the nat-to-127.0.0.54-from-another-interface usecase that was described in a8d09063447568d87288a8e868fe386c1da7ce09 intact. Also note that nat is not supported for the main stub 127.0.0.53 which is why forcing LOOPBACK_IFINDEX was/is fine for that case.

E.g. "Failed to load BPF object: %m" appeared 5 times in the sources. But it is very important to know *which* object we failed to load. This could be guessed, e.g. from surroudning messages or from filename/line metadata, but when we get log messages in bug reports, this might not be available. Let's make the messages distinguishable. While at it, some messages were adjusted a bit. In particular, we shouldn't use internal names like BPFProgram which have no meaning outside of the codebase.

The benefit over using rootlibexecdir is that this path can be multiarch aware, i.e. this path can be architecture qualified. This is something we'd like to make use of in Debian/Ubuntu to make libsystemd-shared co-installable, e.g. for i386 the path would be /usr/lib/i386-linux-gnu/systemd/libsystemd-shared-*.so and for amd64 /usr/lib/x86_64-linux-gnu/systemd/libsystemd-shared-*.so. This will allow for example to install and run systemd-boot/i386 on an amd64 host. It also simplifies/enables cross-building/bootstrapping.

Plymouth and user interaction: Forward the progress to plymouth and support canellation of in progress fsck. Try to connect and send to plymouth (if running) some checked report progress, using direct plymouth protocole. Update message is the following: fsckd::: * num_devices corresponds to the current number of devices being checked (int) * progress corresponds to the current minimum percentage of all devices being checked (float, from 0 to 100) * string is a translated message ready to be displayed by the plymouth theme displaying the information above. It can be overridden by plymouth themes supporting i18n. Grab in fsckd plymouth watch key Control+C, and propagate this cancel request to systemd-fsck which will terminate fsck. Send a message to signal to user what key we are grabbing for fsck cancel. Message is: fsckd-cancel-msg: Where string is a translated string ready to be displayed by the plymouth theme indicating that Control+C can be used to cancel current checks. It can be overridden (matching only fsckd-cancel-msg prefix) for themes supporting i18n. Misc: systemd-fsckd stops on idle when no fsck is connected. Add man page explaining the plymouth theme protocol, usage of the daemon as well as the socket activation part. Adapt existing fsck man page. Note that fsckd had lived in the upstream tree for a while, but was removed.

It's also contradicting core(8), and it's not systemd's place to redefine the kernel definitions of core files. Commit bdfd7b2c now honours the process' RLIMIT_CORE for systemd-coredump. This isn't what RLIMIT_CORE is supposed to do (it limits the size of the core *file*, but the kernel deliberately ignores it for piping), so set a static 2^63 core size limit for systemd-coredump to go back to the previous behaviour (otherwise the change above would break systemd-coredump).

Return false if the current machine's product name is blacklisted. 2. Return false if the current machine's product name does not have a 'laptop' chassis (as per hostnamed) AND is not explicitly whitelisted. 3. Fallback to the default logic if neither (1) nor (2) apply. The blacklist and whitelist database would be stored via a configuration file in /etc/systemd/sleep-products.conf, with its content organized in sections, listing the product names (as taken from the DMI table) we want to blacklist or white list for each sleep operation. Neither this file nor its contents are mandatory, but if it exists, it would look something like this (not all the sections mandatory either): [CanSuspend] BlackListProducts=ProductNameA ProductNameB WhiteListProducts=ProductNameC [CanHibernate] BlackListProducts=ProductNameA ProductNameB ProductNameD [CanHybridSleep] WhiteListProducts=ProductNameA ProductNameE That way we should be able to explicitly blacklist laptop models if we know they have problems, as well as whitelist desktop computers when we now they work fine and want to support them explicitly. https://phabricator.endlessm.com/T4655 --- src/shared/sleep-config.c | 138 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 138 insertions(+) diff --git a/src/shared/sleep-config.c b/src/shared/sleep-config.c index 2d2aa19ac8..e8cd193173 100644 --- a/src/shared/sleep-config.c +++ b/src/shared/sleep-config.c @@ -17,6 +17,8 @@ #include "alloc-util.h" #include "blockdev-util.h" +#include "bus-error.h" +#include "bus-util.h" #include "btrfs-util.h" #include "conf-parser.h" #include "def.h" @@ -28,6 +30,7 @@ #include "log.h" #include "macro.h" #include "path-util.h" +#include "sd-bus.h" #include "sleep-config.h" #include "stat-util.h" #include "stdio-util.h" @@ -102,6 +105,56 @@ int parse_sleep_config(SleepConfig **ret_sleep_config) { return 0; } +static int parse_sleep_products_config(SleepOperation operation, char ***_blacklist, char ***_whitelist) { + + _cleanup_strv_free_ char + **suspend_blacklist = NULL, **suspend_whitelist = NULL, + **hibernate_blacklist = NULL, **hibernate_whitelist = NULL, + **hybrid_blacklist = NULL, **hybrid_whitelist = NULL; + char **blacklist, **whitelist; + + const ConfigTableItem items[] = { + { "CanSuspend", "BlackListProducts", config_parse_strv, 0, &suspend_blacklist }, + { "CanSuspend", "WhiteListProducts", config_parse_strv, 0, &suspend_whitelist }, + { "CanHibernate", "BlackListProducts", config_parse_strv, 0, &hibernate_blacklist }, + { "CanHibernate", "WhiteListProducts", config_parse_strv, 0, &hibernate_whitelist }, + { "CanHybridSleep", "BlackListProducts", config_parse_strv, 0, &hybrid_blacklist }, + { "CanHybridSleep", "WhiteListProducts", config_parse_strv, 0, &hybrid_whitelist }, + {} + }; + + int r; + _cleanup_fclose_ FILE *f; + + f = fopen(PKGSYSCONFDIR "/sleep-products.conf", "re"); + if (!f) + log_full(errno == ENOENT ?

In our current setup ID_FS_TYPE is not set and udisk is unable to detect any filesystem on the CDROM, refusing to mount it using udiskctl (or programmatically). ID_FS_TYPE (among other things) is set by 'blkid' in 60-persistent-storage.rules with the rule: KERNEL=="sr*", ENV{DISK_EJECT_REQUEST}!="?*", \ ENV{ID_CDROM_MEDIA_TRACK_COUNT_DATA}=="?*", \ ENV{ID_CDROM_MEDIA_SESSION_LAST_OFFSET}=="", \ MPORT{builtin}="blkid --noraid" Unfortunately this rule is never matched/executed since ID_CDROM_MEDIA_TRACK_COUNT_DATA is never set. ID_CDROM_MEDIA_TRACK_COUNT_DATA should be set by 'cdrom_id' in 60-cdrom_id.rules but on our system 'cdrom_id /dev/sr0' fails with -EBUSY. The problem is that 'cdrom_id' tries to open /dev/sr0 using O_EXCL. O_EXCL on block devices fails with EBUSY if, and only if, there's someone else also opening the device with O_EXCL [1]. In our case this call fails since we are already booting from /dev/sr0 keeping it already opened with O_EXCL. As suggested here [2] we fix this by not relying anymore on ID_CDROM_MEDIA_TRACK_COUNT_DATA for executing 'blkid' and importing ID_FS_*.

This unit is only active if a boot loader fully supporting the Boot Loader Specificiation is detected (via a LoaderFeatures EFI var), which currently is only true for Endless PAYG images, which use systemd-boot instead of GRUB. This random seed is stored in /boot/loader/random-seed, with /boot/loader being created if it does not exist. The problem here is that in our systemd-boot + OSTree setup on PAYG images we need /boot/loader to be a symbolic link pointing to either /boot/loader.1 or /boot/loader.0 (OSTree requirement) living in the ESP (systemd-boot requirement) which is FAT32 (UEFI spec) and does not support symlinks. To solve that we implemented a fake symlink as a file in /boot/loader.lnk containing the path that should be the /boot/loader target, and taught OSTree about it, giving higher precedence to the real /boot/loader in case it exists. So if systemd-boot-system-token.service creates /boot/loader, most OSTree operations break, because the entries/ directory is not found. Let's disable this service here to avoid that problem. This unit is enabled by the build system at install time instead of using the more traditional approach of having a [Install] section and using systemctl and the preset system, so we have to disable it in units/meson.build. There is also an accompanying commit in the packaging branch that removes the installation of the symbolic link in sysinit.target.wants/systemd-boot-system-token.service. https://phabricator.endlessm.com/T29475 --- units/meson.build | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/units/meson.build b/units/meson.build index 81bb9a8792..f4ef635d0c 100644 --- a/units/meson.build +++ b/units/meson.build @@ -106,8 +106,7 @@ units = [ ['systemd-ask-password-wall.path', '', 'multi-user.target.wants/'], ['systemd-ask-password-wall.service', ''], - ['systemd-boot-system-token.service', 'HAVE_GNU_EFI', - 'sysinit.target.wants/'], + ['systemd-boot-system-token.service', 'HAVE_GNU_EFI'], ['systemd-boot-update.service', 'HAVE_GNU_EFI'], ['systemd-coredump.socket', 'ENABLE_COREDUMP', 'sockets.target.wants/'], From 09596e4cb7e2e12232e8055319b5134a1276c16b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jo=C3=A3o=20Paulo=20Rechi=20Vita?= Date: Mon, 1 Feb 2021 11:12:30 -0800 Subject: [PATCH 84/92] [Endless] Revert "test-mountpoint-util: run test in private mount namespace" This reverts commit af918c481864116fdf92eceb3376a014053eaf5f.

Debian's policy is to never clean-up /var/tmp to keep consistency with the SysV init system. Flatpak creates temporary files in /var/tmp during app updates but does not remove them on error, to avoid re-downloading them on a future update attempt, and expects these files to be automatically cleaned-up by the system eventually, according to the site's policy. With this policy in place these files are never removed, wasting the user's storage space. Revert this commit back to upstream's default policy of cleaning up /tmp every 10 days and /var/tmp every 30 days. https://phabricator.endlessm.com/T23762 https://phabricator.endlessm.com/T33887 --- tmpfiles.d/tmp.conf | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tmpfiles.d/tmp.conf b/tmpfiles.d/tmp.conf index 39cb5cccaa..fe5225d751 100644 --- a/tmpfiles.d/tmp.conf +++ b/tmpfiles.d/tmp.conf @@ -8,5 +8,5 @@ # See tmpfiles.d(5) for details # Clear tmp directories separately, to make them easier to override -D /tmp 1777 root root - -#q /var/tmp 1777 root root 30d +q /tmp 1777 root root 10d +q /var/tmp 1777 root root 30d From 75e4ccd591a7911c6b99a94a2aa075e23b97b1aa Mon Sep 17 00:00:00 2001 From: Jan Janssen Date: Sun, 9 Oct 2022 17:16:12 +0200 Subject: [PATCH 90/92] meson: Fix build with --optimization=plain Note that -O0 is deliberately filtered out as we have to compile with at least -O1 due to #24202.

This is a weaker guarantee but likely the same for the vast majority of systems. Allowing the ESP automount in this case helps break a dependency loop. Existing boot loaders can be changed to set LoaderDevicePartUUID, but they can't be delivered to existing systems if the ESP is not mounted.
