2023-04-14wifi: iwlwifi: pcie: Fix integer overflow in iwl_write_to_user_bufHyunwoo Kim
An integer overflow occurs in the iwl_write_to_user_buf() function, which is called by the iwl_dbgfs_monitor_data_read() function. static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count, void *buf, ssize_t *size, ssize_t *bytes_copied) { int buf_size_left = count - *bytes_copied; buf_size_left = buf_size_left - (buf_size_left % sizeof(u32)); if (*size > buf_size_left) *size = buf_size_left; If the user passes a SIZE_MAX value to the "ssize_t count" parameter, the ssize_t count parameter is assigned to "int buf_size_left". Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a negative number, so "*size" is assigned "buf_size_left" and goes into the third argument of the copy_to_user function, causing a heap overflow. This is not a security vulnerability because iwl_dbgfs_monitor_data_read() is a debugfs operation with 0400 privileges.

2023-04-14wifi: iwlwifi: pcie: work around ROM bug on AX210 integratedJohannes Berg
On 22000 and AX210 devices, there's a ROM bug that causes it to set invalid LTR settings. On 22000 and AX210 non-integrated we can fix up these settings from the driver (as done in the code here), but on AX210 integrated these registers are not available to the driver. Attempt to work around the issue by spinning while the IML is being loaded, the IML will then reprogram the LTR values itself after it's loaded, so only the brief IML load (which the ROM is doing) is affected.

Newer firmware versions will support a new queue allocation command, in order to deal with MLD where multiple stations are used for a single queue. Add support for the new command. This requires some refactoring of the queue allocation API, which now gets - the station mask instead of the station ID - the flags without the "enable" flag, since that's no longer used in the new API Additionally, this new API now requires that we remove queues before removing a station, the firmware will no longer do that internally.

2022-02-18iwlwifi: pcie: adjust to Bz completion descriptorJohannes Berg
The Bz devices got a new completion descriptor again since we only ever really used 4 out of 32 bytes anyway. Adjust the code to deal with that. Note that the intention was to reduce the size, but the hardware was implemented wrongly. While at it, do some cleanups and remove the union to simplify the code, clean up iwl_pcie_free_bd_size() to no longer need an argument and add iwl_pcie_used_bd_size() with the logic to selct completion descriptor size.

2022-02-18iwlwifi: propagate (const) type qualifierBjoern A. Zeeb
Most of this change is a continuation of commit 403ea939ea6a ("iwlwifi: dbg: Mark ucode tlv data as const") propagating the (const) type qualifier for ucode based tlv data to avoid having the impression that it is writeable. The other part of the change preserves the (const) type qualifier over casts and function calls where it was previously lost. Both changes are needed to avoid compile time errors on system with more strict error settings, in this case found with clang on FreeBSD. Sponsored by: The FreeBSD Foundation Signed-off-by: Bjoern A.

2022-02-18iwlwifi: de-const properly where neededBjoern A. Zeeb
In order to de-const variables simply casting through (void *) is not enough: "cast from 'const .. *' to 'void *' drops const qualifier". Cast through (uintptr_t) as well [1] to make this compile on systems with more strict requirements. In addition passing const void *data to dma_map_single() also drops the (const) qualifier. De-constify on variable on assignment which may be overwritten later. In either case the (void *) cast to dma_map_single() is not needed (anymore) either.

In some rare cases when the HW is in a bad state, we may get this interrupt when prph_info is not set yet. Then we will try to dereference it to check the sleep_notif element, which will cause an oops. Fix that by ignoring the interrupt if prph_info is not set yet.

2021-12-21iwlwifi: Read the correct addresses when getting the crf idMatti Gottlieb
The original implementation checked the HW family, and as a result of that used different addresses for the prph registers. The old HWs addresses start with 0xa****** and the newer ones start with 0xd******. For this there are iwl_read/write_umac_prph functions that just add the diff in the address automatically (in this case 0x300000), so the code will be common for all HWs In the original implementation the address given already had the 0xd****** causing the address to become 0x10***** (after adding the offset) Change the registers to start with 0xa*****.
