2021-08-26staging: r8188eu: change declaration of Efuse_Read1ByteFromFakeContentPhillip Potter
Remove forward declaration of Efuse_Read1ByteFromFakeContent function from core/rtw_efuse.c, as the function is defined in full directly after this and therefore this forward declaration is redundant. In addition, convert the storage class of the function to static, as the function is only used with rtw_efuse.c, and tidy up the signature alignment. Acked-by: Fabio M.

2021-08-26staging/rtl8192u: Prefer kcalloc over open coded arithmeticLen Baker
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. In this case these aren't actually dynamic sizes: both sides of the multiplication are constant values. However it is best to refactor these anyway, just to keep the open-coded math idiom out of code. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function.

2021-08-26net: dsa: hellcreek: Adjust schedule look ahead windowKurt Kanzenbach
Traffic schedules can only be started up to eight seconds within the future. Therefore, the driver periodically checks every two seconds whether the admin base time provided by the user is inside that window. If so the schedule is started. Otherwise the check is deferred. However, according to the programming manual the look ahead window size should be four - not eight - seconds. By using the proposed value of four seconds starting a schedule at a specified admin base time actually works as expected.

2021-08-26ionic: sync the filters in the work taskShannon Nelson
In order to separate the atomic needs of __dev_uc_sync() and __dev_mc_sync() from the safe rx_mode handling, we need to have the ndo handler manipulate the driver's filter list, and later have the driver sync the filters to the firmware, outside of the atomic context. Here we put __dev_mc_sync() and __dev_uc_sync() back into the ndo callback to give them their netif_addr_lock context and have them update the driver's filter list, flagging changes that should be made to the device filter list. Later, in the rx_mode handler, we read those hints and sync up the device's list as needed. It is possible for multiple add/delete requests to come from the stack before the rx_mode task processes the list, but the handling of the sync status flag should keep everything sorted correctly. For example, if a delete of an existing filter is followed by another add before the rx_mode task is run, as can happen when going in and out of a bond, the add will cancel the delete and no actual changes will be sent to the device. We also add a check in the watchdog to see if there are any stray unsync'd filters, possibly left over from a filter overflow and waiting to get sync'd after some other filter gets removed to make room.

2021-08-26ionic: flatten calls to set-rx-modeShannon Nelson
Since only two functions call through ionic_set_rx_mode(), one that can sleep and one that can't, we can split the function and put the bits of code into the callers. This removes an unnecessary calling layer. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-08-26ionic: remove old work task typesShannon Nelson
With the move of mac filter handling to outside of the ndo_rx_mode context using the IONIC_DW_TYPE_RX_MODE, we no longer are using IONIC_DW_TYPE_RX_ADDR_ADD and IONIC_DW_TYPE_RX_ADDR_DEL and they can be removed.

2021-08-26staging: wlan-ng: Avoid duplicate header in tx/rx framesKees Cook
Instead of open-coding the same header details in the tx/rx frames, directly include the actual struct. Rename associated variables to the more verbose of the two versions. This also has the benefit of being able to replace a field-spanning memcpy() with a direct assignment, helping clear the way for coming FORTIFY_SOURCE improvements. "diffoscope" reports no object code differences after this change, excepting the selection of different registers when switching from memcpy() to direct assignment: --- drivers/staging/wlan-ng/prism2usb.o.before +++ drivers/staging/wlan-ng/prism2usb.o.after ├── objdump --line-numbers --disassemble --demangle --reloc --no-show-raw-insn --section=.text {} │ @@ -4887,24 +4887,24 @@ │ sub %rdi,%rcx │ add $0x3c,%ecx │ shr $0x3,%ecx │ rep stos %rax,%es:(%rdi) │ mov $0x8,%eax │ movl $0x123,0x23e(%rbx) │ mov %ax,0x244(%rbx) │ - mov (%rdx),%rcx │ - mov %rcx,0x246(%rbx) │ - mov 0x8(%rdx),%rcx │ - mov %rcx,0x24e(%rbx) │ - mov 0x10(%rdx),%rcx │ - mov %rcx,0x256(%rbx) │ - mov 0x18(%rdx),%ecx │ - mov %ecx,0x25e(%rbx) │ - movzwl 0x1c(%rdx),%edx │ - mov %dx,0x262(%rbx) │ + mov (%rdx),%rax │ + mov %rax,0x246(%rbx) │ + mov 0x8(%rdx),%rax │ + mov %rax,0x24e(%rbx) │ + mov 0x10(%rdx),%rax │ + mov %rax,0x256(%rbx) │ + mov 0x18(%rdx),%eax │ + mov %eax,0x25e(%rbx) │ + movzwl 0x1c(%rdx),%eax │ + mov %ax,0x262(%rbx) │ cmpq $0x0,0x0(%rbp) │ movzwl 0x70(%rsi),%eax │ je 477a <hfa384x_drvr_txframe+0xba> │ add $0x8,%eax │ mov $0x44,%r12d │ mov %ax,0x264(%rbx) │ mov 0x70(%r13),%edx Cc: Romain Perier <romain.perier@gmail.com> Cc: Allen Pais <apais@linux.microsoft.com> Cc: Ivan Safonov <insafonov@gmail.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: linux-staging@lists.linux.dev Signed-off-by: Kees Cook <keescook@chromium.org> Link: https://lore.kernel.org/r/20210819174537.3499227-3-keescook@chromium.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-08-26staging: wlan-ng: Remove pointless a3/a4 unionKees Cook
There is no need for the a3/a4 union. The two structs are identical except for the addition of a4. Excepting one place, the structs are only ever used in the union, and the union is always allocated at full size. The one instance of the a3-specific struct can be replaced with the full version, as no sizing information is used. Replace the union with the a4 version of the struct. "diffoscope" reports there are no object code differences after this change.
