2024-05-10powerpc/fadump: setup additional parameters for dump capture kernelHari Bathini
For fadump case, passing additional parameters to dump capture kernel helps in minimizing the memory footprint for it and also provides the flexibility to disable components/modules, like hugepages, that are hindering the boot process of the special dump capture environment. Set up a dedicated parameter area to be passed to the capture kernel. This area type is defined as RTAS_FADUMP_PARAM_AREA. Sysfs attribute '/sys/kernel/fadump/bootargs_append' is exported to the userspace to specify the additional parameters to be passed to the capture kernel Signed-off-by: Hari Bathini <hbathini@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20240509115755.519982-3-hbathini@linux.ibm.com
2024-05-10powerpc/pseries/fadump: add support for multiple boot memory regionsHari Bathini
Currently, fadump on pseries assumes a single boot memory region even though f/w supports more than one boot memory region. Add support for more boot memory regions to make the implementation flexible for any enhancements that introduce other region types. For this, rtas memory structure for fadump is updated to have multiple boot memory regions instead of just one. Additionally, methods responsible for creating the fadump memory structure during both the first and second kernel boot have been modified to take these multiple boot memory regions into account. Also, a new callback has been added to the fadump_ops structure to get the maximum boot memory regions supported by the platform.

2024-05-10fcntl: add F_DUPFD_QUERY fcntl()Linus Torvalds
Often userspace needs to know whether two file descriptors refer to the same struct file. For example, systemd uses this to filter out duplicate file descriptors in it's file descriptor store (cf. [1]) and vulkan uses it to compare dma-buf fds (cf. [2]). The only api we provided for this was kcmp() but that's not generally available or might be disallowed because it is way more powerful (allows ordering of file pointers, operates on non-current task) etc. So give userspace a simple way of comparing two file descriptors for sameness adding a new fcntl() F_DUDFD_QUERY.

2024-05-10media: bcm2835-unicam: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

The btf_features list can be used for pahole v1.26 and later - it is useful because if a feature is not yet implemented it will not exit with a failure message. This will allow us to add feature requests to the pahole options without having to check pahole versions in future; if the version of pahole supports the feature it will be added.

2024-05-09Merge branch 'use network helpers, part 4'Martin KaFai Lau
Geliang Tang says: ==================== From: Geliang Tang <tanggeliang@kylinos.cn> This patchset adds post_socket_cb pointer into struct network_helper_opts to make start_server_addr() helper more flexible. With these modifications, many duplicate codes can be dropped. Patches 1-3 address Martin's comments in the previous series. ==================== Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>
2024-05-09selftests/bpf: Drop get_port in test_tcp_check_syncookieGeliang Tang
The arguments "addr" and "len" of run_test() have dropped. This makes function get_port() useless. Drop it from test_tcp_check_syncookie_user.c.

2024-05-09selftests/bpf: Use connect_to_fd in test_tcp_check_syncookieGeliang Tang
This patch uses public helper connect_to_fd() exported in network_helpers.h instead of the local defined function connect_to_server() in test_tcp_check_syncookie_user.c. This can avoid duplicate code. Then the arguments "addr" and "len" of run_test() become useless, drop them too.

2024-05-09selftests/bpf: Use start_server_addr in test_tcp_check_syncookieGeliang Tang
Include network_helpers.h in test_tcp_check_syncookie_user.c, use public helper start_server_addr() in it instead of the local defined function start_server(). This can avoid duplicate code. Add two helpers v6only_true() and v6only_false() to set IPV6_V6ONLY sockopt to true or false, set them to post_socket_cb pointer of struct network_helper_opts, and pass it to start_server_setsockopt(). In order to use functions defined in network_helpers.c, Makefile needs to be updated too.

2024-05-09selftests/bpf: Add post_socket_cb for network_helper_optsGeliang Tang
__start_server() sets SO_REUSPORT through setsockopt() when the parameter 'reuseport' is set. This patch makes it more flexible by adding a function pointer post_socket_cb into struct network_helper_opts. The 'const struct post_socket_opts *cb_opts' args in the post_socket_cb is for the future extension. The 'reuseport' parameter can be dropped. Now the original start_reuseport_server() can be implemented by setting a newly defined reuseport_cb() function pointer to post_socket_cb filed of struct network_helper_opts.

2024-05-09hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to ↵Uwe Kleine-König
0 (part 2) These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. This is a follow up to commit d8a66f3621c2 ("hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0") which I created before identifying a few corner cases in my conversion script.

2024-05-09selftest: epoll_busy_poll: epoll busy poll testsJoe Damato
Add a simple test for the epoll busy poll ioctls, using the kernel selftest harness. This test ensures that the ioctls have the expected return codes and that the kernel properly gets and sets epoll busy poll parameters. The test can be expanded in the future to do real busy polling (provided another machine to act as the client is available).

Update tpm2_load_context() to return -EINVAL on integrity failures and use this as a signal when loading the NULL context that something might be wrong. If the signal fails, check the name of the NULL primary against the one stored in the chip data and if there is a mismatch disable the TPM because it is likely to have suffered a reset attack.
