BugLink: https://bugs.launchpad.net/bugs/1860681 commit 529244bd upstream. Doing an add/remove/add on a SCSI device in an enclosure leads to an oops caused by poisoned values in the enclosure device list pointers. The reason is because we are keeping the enclosure device across the enclosed device add/remove/add but the current code is doing a device_add/device_del/device_add on it. This is the wrong thing to do in sysfs, so fix it by not doing a device_del on the enclosure device simply because of a hot remove of the drive in the slot.

BugLink: https://bugs.launchpad.net/bugs/1860681 commit a1078e82 upstream. Instead of trying to allocate pages with GFP_USER in add_ballooned_pages() check the available free memory via si_mem_available(). GFP_USER is far less limiting memory exhaustion than the test via si_mem_available(). This will avoid dom0 running out of memory due to excessive foreign page mappings especially on ARM and on x86 in PVH mode, as those don't have a pre-ballooned area which can be used for foreign mappings. As the normal ballooning suffers from the same problem don't balloon down more than si_mem_available() pages in one iteration. At the same time limit the default maximum number of retries. This is part of XSA-300. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 34501219 upstream. LINE6 drivers allocate the buffers based on the value returned from usb_maxpacket() calls. The manipulated device may return zero for this, and this results in the kmalloc() with zero size (and it may succeed) while the other part of the driver code writes the packet data with the fixed size -- which eventually overwrites. This patch adds a simple sanity check for the invalid buffer size for avoiding that problem. Reported-by: syzbot+219f00fb49874dcaea17@syzkaller.appspotmail.com Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 6e41e225 upstream. The syzbot fuzzer found a bug in the p54 USB wireless driver. The issue involves a race between disconnect and the firmware-loader callback routine, and it has several aspects. One big problem is that when the firmware can't be loaded, the callback routine tries to unbind the driver from the USB _device_ (by calling device_release_driver) instead of from the USB _interface_ to which it is actually bound (by calling usb_driver_release_interface). The race involves access to the private data structure. The driver's disconnect handler waits for a completion that is signalled by the firmware-loader callback routine. As soon as the completion is signalled, you have to assume that the private data structure may have been deallocated by the disconnect handler -- even if the firmware was loaded without errors. However, the callback routine does access the private data several times after that point. Another problem is that, in order to ensure that the USB device structure hasn't been freed when the callback routine runs, the driver takes a reference to it. This isn't good enough any more, because now that the callback routine calls usb_driver_release_interface, it has to ensure that the interface structure hasn't been freed. Finally, the driver takes an unnecessary reference to the USB device structure in the probe function and drops the reference in the disconnect handler. This extra reference doesn't accomplish anything, because the USB core already guarantees that a device structure won't be deallocated while a driver is still bound to any of its interfaces. To fix these problems, this patch makes the following changes: Call usb_driver_release_interface() rather than device_release_driver(). Don't signal the completion until after the important information has been copied out of the private data structure, and don't refer to the private data at all thereafter. Lock udev (the interface's parent) before unbinding the driver instead of locking udev->parent. During the firmware loading process, take a reference to the USB interface instead of the USB device. Don't take an unnecessary reference to the device during probe (and then don't drop it during disconnect). Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 3e493173 upstream. The Layer 2 Update frame is used to update bridges when a station roams to another AP even if that STA does not transmit any frames after the reassociation. This behavior was described in IEEE Std 802.11F-2003 as something that would happen based on MLME-ASSOCIATE.indication, i.e., before completing 4-way handshake. However, this IEEE trial-use recommended practice document was published before RSN (IEEE Std 802.11i-2004) and as such, did not consider RSN use cases. Furthermore, IEEE Std 802.11F-2003 was withdrawn in 2006 and as such, has not been maintained amd should not be used anymore. Sending out the Layer 2 Update frame immediately after association is fine for open networks (and also when using SAE, FT protocol, or FILS authentication when the station is actually authenticated by the time association completes). However, it is not appropriate for cases where RSN is used with PSK or EAP authentication since the station is actually fully authenticated only once the 4-way handshake completes after authentication and attackers might be able to use the unauthenticated triggering of Layer 2 Update frame transmission to disrupt bridge behavior. Fix this by postponing transmission of the Layer 2 Update frame from station entry addition to the point when the station entry is marked authorized. Similarly, send out the VLAN binding update only if the STA entry has already been authorized. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1859865 commit 1b789577 upstream. We get crash when the targets checkentry function tries to make use of the network namespace pointer for arptables. When the net pointer got added back in 2010, only ip/ip6/ebtables were changed to initialize it, so arptables has this set to NULL. This isn't a problem for normal arptables because no existing arptables target has a checkentry function that makes use of par->net. However, direct users of the setsockopt interface can provide any target they want as long as its registered for ARP or UNPSEC protocols. syzkaller managed to send a semi-valid arptables rule for RATEEST target which is enough to trigger NULL deref: kasan: GPF could be caused by NULL-ptr deref or user memory access general protection fault: 0000 [#1] PREEMPT SMP KASAN RIP: xt_rateest_tg_checkentry+0x11d/0xb40 net/netfilter/xt_RATEEST.c:109 [..] xt_check_target+0x283/0x690 net/netfilter/x_tables.c:1019 check_target net/ipv4/netfilter/arp_tables.c:399 [inline] find_check_entry net/ipv4/netfilter/arp_tables.c:422 [inline] translate_table+0x1005/0x1d70 net/ipv4/netfilter/arp_tables.c:572 do_replace net/ipv4/netfilter/arp_tables.c:977 [inline] do_arpt_set_ctl+0x310/0x640 net/ipv4/netfilter/arp_tables.c:1456 Fixes: add67461 ("netfilter: add struct net * to target parameters") Reported-by: syzbot+d7358a458d8a81aee898@syzkaller.appspotmail.com Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1859865 commit 2548288b upstream. It turns out that even though endpoints with a maxpacket length of 0 aren't useful for data transfer, the descriptors do serve other purposes. In particular, skipping them will also skip over other class-specific descriptors for classes such as UVC. This unexpected side effect has caused some UVC cameras to stop working. In addition, the USB spec requires that when isochronous endpoint descriptors are present in an interface's altsetting 0 (which is true on some devices), the maxpacket size _must_ be set to 0. Warning about such things seems like a bad idea. This patch updates an earlier commit which would log a warning and skip these endpoint descriptors. Now we only log a warning, and we don't even do that for isochronous endpoints in altsetting 0. We don't need to worry about preventing endpoints with maxpacket = 0 from ever being used for data transfers; usb_submit_urb() already checks for this. Reported-and-tested-by:

BugLink: https://bugs.launchpad.net/bugs/1859865 commit 273f6329 upstream. If the serial device is disconnected and reconnected, it re-enumerates properly but does not link it. fwiw, linking means just saving the port index, so allow it always as there is no harm in saving the same value again even if it tries to relink with the same port.

BugLink: https://bugs.launchpad.net/bugs/1859865 commit fb2b9001 upstream. There seems to be a race condition in tty drivers and I could see on many boot cycles a NULL pointer dereference as tty_init_dev() tries to do 'tty->port->itty = tty' even though tty->port is NULL. 'tty->port' will be set by the driver and if the driver has not yet done it before we open the tty device we can get to this situation. By adding some extra debug prints, I noticed that: 6.650130: uart_add_one_port 6.663849: register_console 6.664846: tty_open 6.674391: tty_init_dev 6.675456: tty_port_link_device uart_add_one_port() registers the console, as soon as it registers, the userspace tries to use it and that leads to tty_open() but uart_add_one_port() has not yet done tty_port_link_device() and so tty->port is not yet configured when control reaches tty_init_dev(). Further look into the code and tty_port_link_device() is done by uart_add_one_port(). After registering the console uart_add_one_port() will call tty_port_register_device_attr_serdev() and tty_port_link_device() is called from this. Call add tty_port_link_device() before uart_configure_port() is done and add a check in tty_port_link_device() so that it only links the port if it has not been done yet. Suggested-by:
