2020-04-21rtw88: 8723d: Add RF read/write opsPing-Ke Shih
8723D use SIPI to indirectly read RF register instead of directly read, so introduce a new struct rtw_rf_sipi_addr and new function rtw_phy_read_rf_sipi(). Since other chips don't use the new function, only 8723D needs to fill struct rtw_rf_sipi_addr in rtw_chip_info. Because there are two kinds of functions for reading RF registers now, change rtw_phy_read_rf() to chip->ops->read_rf() in rtw_phy_write_rf_reg_sipi() so that we can switch tp proper RF read functions depends on the type of the chip. Though 8723D is an 1x1 chip, it has two RF PHY and we can switch to one of them, and that should be configured properly. Hence, add a fix_rf_phy_num to struct rtw_chip_info to allow driver to set one of the PHY's registers for 8723D, even it is only 1x1. Another variable rf_phy_num is introduced to keep the constraint number of RF path we can access, and its value is: rf_phy_num = (fix_rf_phy_num ? fix_rf_phy_num : rf_path_num) Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Zong-Zhe Yang <kevin_yang@realtek.com> Signed-off-by: Yan-Hsuan Chuang <yhchuang@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200420055054.14592-5-yhchuang@realtek.com

2020-04-21rtw88: 8723d: add beamform wrapper functionsPing-Ke Shih
8723D doesn't support beamform because rtw88 only supports VHT beamform but 8723d doesn't have VHT capability. Though 8723d doesn't support beamform, BSS_CHANGED_MU_GROUPS is still marked as changed when doing disassociation. So, add wrapper functions for all beamform ops to make sure they aren't NULL before calling.

2020-04-14b43legacy: Fix case where channel status is corruptedLarry Finger
This patch fixes commit 75388acd0cd8 ("add mac80211-based driver for legacy BCM43xx devices") In https://bugzilla.kernel.org/show_bug.cgi?id=207093, a defect in b43legacy is reported. Upon testing, thus problem exists on PPC and X86 platforms, is present in the oldest kernel tested (3.2), and has been present in the driver since it was first added to the kernel. The problem is a corrupted channel status received from the device. Both the internal card in a PowerBook G4 and the PCMCIA version (Broadcom BCM4306 with PCI ID 14e4:4320) have the problem. Only Rev, 2 (revision 4 of the 802.11 core) of the chip has been tested. No other devices using b43legacy are available for testing. Various sources of the problem were considered. Buffer overrun and other sources of corruption within the driver were rejected because the faulty channel status is always the same, not a random value. It was concluded that the faulty data is coming from the device, probably due to a firmware bug. As that source is not available, the driver must take appropriate action to recover. At present, the driver reports the error, and them continues to process the bad packet. This is believed that to be a mistake, and the correct action is to drop the correpted packet.

2020-04-10mm/vma: introduce VM_ACCESS_FLAGSAnshuman Khandual
There are many places where all basic VMA access flags (read, write, exec) are initialized or checked against as a group. One such example is during page fault. Existing vma_is_accessible() wrapper already creates the notion of VMA accessibility as a group access permissions. Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which will not only reduce code duplication but also extend the VMA accessibility concept in general.
