BugLink: https://bugs.launchpad.net/bugs/1892822 commit 1c9df907 upstream. Daniel Díaz and Kees Cook independently reported that commit f227e3ec ("random32: update the net random state on interrupt and activity") broke arm64 due to a circular dependency on include files since the addition of percpu.h in random.h. The correct fix would definitely be to move all the prandom32 stuff out of random.h but for backporting, a smaller solution is preferred. This one replaces linux/percpu.h with asm/percpu.h, and this fixes the problem on x86_64, arm64, arm, and mips. Note that moving percpu.h around didn't change anything and that removing it entirely broke differently. When backporting, such options might still be considered if this patch fails to help. [ It turns out that an alternate fix seems to be to just remove the troublesome <asm/pointer_auth.h> remove from the arm64 <asm/smp.h> that causes the circular dependency. But we might as well do the whole belt-and-suspenders thing, and minimize inclusion in <linux/random.h> too. Either will fix the problem, and both are good changes. - Linus ] Reported-by:

BugLink: https://bugs.launchpad.net/bugs/1892822 commit f227e3ec upstream. This modifies the first 32 bits out of the 128 bits of a random CPU's net_rand_state on interrupt or CPU activity to complicate remote observations that could lead to guessing the network RNG's internal state. Note that depending on some network devices' interrupt rate moderation or binding, this re-seeding might happen on every packet or even almost never. In addition, with NOHZ some CPUs might not even get timer interrupts, leaving their local state rarely updated, while they are running networked processes making use of the random state. For this reason, we also perform this update in update_process_times() in order to at least update the state when there is user or system activity, since it's the only case we care about.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit bdd65589 upstream. 0day reported a possible circular locking dependency: Chain exists of: &irq_desc_lock_class --> console_owner --> &port_lock_key Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&port_lock_key); lock(console_owner); lock(&port_lock_key); lock(&irq_desc_lock_class); The reason for this is a printk() in the i8259 interrupt chip driver which is invoked with the irq descriptor lock held, which reverses the lock operations vs. printk() from arbitrary contexts. Switch the printk() to printk_deferred() to avoid that. Reported-by:

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit c2c63310 ] There's a potential race in xennet_remove(); this is what the driver is doing upon unregistering a network device: 1. state = read bus state 2. if state is not "Closed": 3. request to set state to "Closing" 4. wait for state to be set to "Closing" 5. request to set state to "Closed" 6. wait for state to be set to "Closed" If the state changes to "Closed" immediately after step 1 we are stuck forever in step 4, because the state will never go back from "Closed" to "Closing". Make sure to check also for state == "Closed" in step 4 to prevent the deadlock. Also add a 5 sec timeout any time we wait for the bus state to change, to avoid getting stuck forever in wait_event().

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit 0db9254d ] This reverts commit d358def7. There are two issues with "i2c: cadence: Fix the hold bit setting" commit. 1. In case of combined message request from user space, when the HOLD bit is cleared in cdns_i2c_mrecv function, a STOP condition is sent on the bus even before the last message is started. This is because when the HOLD bit is cleared, the FIFOS are empty and there is no pending transfer. The STOP condition should occur only after the last message is completed. 2. The code added by the commit is redundant. Driver is handling the setting/clearing of HOLD bit in right way before the commit. The setting of HOLD bit based on 'bus_hold_flag' is taken care in cdns_i2c_master_xfer function even before cdns_i2c_msend/cdns_i2c_recv functions. The clearing of HOLD bit is taken care at the end of cdns_i2c_msend and cdns_i2c_recv functions based on bus_hold_flag and byte count. Since clearing of HOLD bit is done after the slave address is written to the register (writing to address register triggers the message transfer), it is ensured that STOP condition occurs at the right time after completion of the pending transfer (last message).

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit 015c5d5e ] According to the report of [1], this driver is possible to cause the following error in ravb_tx_timeout_work(). ravb e6800000.ethernet ethernet: failed to switch device to config mode This error means that the hardware could not change the state from "Operation" to "Configuration" while some tx and/or rx queue are operating. After that, ravb_config() in ravb_dmac_init() will fail, and then any descriptors will be not allocaled anymore so that NULL pointer dereference happens after that on ravb_start_xmit(). To fix the issue, the ravb_tx_timeout_work() should check the return values of ravb_stop_dma() and ravb_dmac_init(). If ravb_stop_dma() fails, ravb_tx_timeout_work() re-enables TX and RX and just exits. If ravb_dmac_init() fails, just exits.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit 4becb7ee upstream. x25_connect() invokes x25_get_neigh(), which returns a reference of the specified x25_neigh object to "x25->neighbour" with increased refcnt. When x25 connect success and returns, the reference still be hold by "x25->neighbour", so the refcount should be decreased in x25_disconnect() to keep refcount balanced. The reference counting issue happens in x25_disconnect(), which forgets to decrease the refcnt increased by x25_get_neigh() in x25_connect(), causing a refcnt leak. Fix this issue by calling x25_neigh_put() before x25_disconnect() returns. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit 033724d6 ] syzbot is reporting general protection fault in bitfill_aligned() [1] caused by integer underflow in bit_clear_margins(). The cause of this problem is when and how do_vc_resize() updates vc->vc_{cols,rows}. If vc_do_resize() fails (e.g. kzalloc() fails) when var.xres or var.yres is going to shrink, vc->vc_{cols,rows} will not be updated. This allows bit_clear_margins() to see info->var.xres < (vc->vc_cols * cw) or info->var.yres < (vc->vc_rows * ch). Unexpectedly large rw or bh will try to overrun the __iomem region and causes general protection fault. Also, vc_resize(vc, 0, 0) does not set vc->vc_{cols,rows} = 0 due to new_cols = (cols ? cols : vc->vc_cols); new_rows = (lines ? lines : vc->vc_rows); exception. Since cols and lines are calculated as cols = FBCON_SWAP(ops->rotate, info->var.xres, info->var.yres); rows = FBCON_SWAP(ops->rotate, info->var.yres, info->var.xres); cols /= vc->vc_font.width; rows /= vc->vc_font.height; vc_resize(vc, cols, rows); in fbcon_modechanged(), var.xres < vc->vc_font.width makes cols = 0 and var.yres < vc->vc_font.height makes rows = 0. This means that const int fd = open("/dev/fb0", O_ACCMODE); struct fb_var_screeninfo var = { }; ioctl(fd, FBIOGET_VSCREENINFO, &var); var.xres = var.yres = 1; ioctl(fd, FBIOPUT_VSCREENINFO, &var); easily reproduces integer underflow bug explained above. Of course, callers of vc_resize() are not handling vc_do_resize() failure is bad. But we can't avoid vc_resize(vc, 0, 0) which returns 0. Therefore, as a band-aid workaround, this patch checks integer underflow in "struct fbcon_ops"->clear_margins call, assuming that vc->vc_cols * vc->vc_font.width and vc->vc_rows * vc->vc_font.heigh do not cause integer overflow.

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit eec13b42 ] Unprivileged memory accesses generated by the so-called "translated" instructions (e.g. LDRT) in kernel mode can cause user watchpoints to fire unexpectedly. In such cases, the hw_breakpoint logic will invoke the user overflow handler which will typically raise a SIGTRAP back to the current task. This is futile when returning back to the kernel because (a) the signal won't have been delivered and (b) userspace can't handle the thing anyway. Avoid invoking the user overflow handler for watchpoints triggered by kernel uaccess routines, and instead single-step over the faulting instruction as we would if no overflow handler had been installed.

BugLink: https://bugs.launchpad.net/bugs/1861284 Add new dkms-build scripting which prepares a kernel headers tree and then builds specified DKMS packages against those headers. The resulting .kos are then incorporated into the specified package, including signing them into this kernels module signing key. This allows them to be loaded in a secure-boot environment.

BugLink: https://bugs.launchpad.net/bugs/1890796 In commit ed17b8d3 ("xfrm: fix a warning in xfrm_policy_insert_list"), it would take 'priority' to make a policy unique, and allow duplicated policies with different 'priority' to be added, which is not expected by userland, as Tobias reported in strongswan. To fix this duplicated policies issue, and also fix the issue in commit ed17b8d3 ("xfrm: fix a warning in xfrm_policy_insert_list"), when doing add/del/get/update on user interfaces, this patch is to change to look up a policy with both mark and mask by doing: mark.v == pol->mark.v && mark.m == pol->mark.m and leave the check: (mark & pol->mark.m) == pol->mark.v for tx/rx path only. As the userland expects an exact mark and mask match to manage policies. v1->v2: - make xfrm_policy_mark_match inline and fix the changelog as Tobias suggested. Fixes: 295fae56 ("xfrm: Allow user space manipulation of SPD mark") Fixes: ed17b8d3 ("xfrm: fix a warning in xfrm_policy_insert_list") Reported-by:
