* MFC r261491 (by ambrisko):Mark Johnston2014-08-272-14/+26
| | | | | | | | | | | | | | | | | | | | | | | | | Add a tunable "hw.mfi.mrsas_enable" to allow mfi(4) to drop priority and allow mrsas(4) from LSI to attach to newer LSI cards that are support by mrsas(4). If mrsas(4) is not loaded into the system at boot then mfi(4) will always attach. If a modified mrsas(4) is loaded in the system. That modification is return "-30" in it's probe since that is between BUS_PROBE_DEFAULT and BUS_PROBE_LOW_PRIORITY. This option is controller by a new probe flag "MFI_FLAGS_MRSAS" in mfi_ident that denotes cards that should work with mrsas(4). New entries that should have this option. This is the first step to get mrsas(4) checked into FreeBSD and to avoid collision with people that use mrsas(4) from LSI. Since mfi(4) takes priority, then mrsas(4) users need to rebuild GENERIC. Using the .disabled="1" method doesn't work since that blocks attaching and the probe gave it to mfi(4). MFC r267451 (by delphij): Correct variable for loader tunable variable hw.mfi.mrsas_enable.

| | | | | | | | | | | Add support for MegaRAID Fury cards. The main change needed to boot from a 9341-4i controller was to ensure that scatter/gather lists are ended with an end-of-list marker. Both the mrsas and Linux megaraid_sas drivers use this marker with Invader cards as well, so we do the same thing, though it is apparently not strictly necessary.

* Merge r254263:Scott Long2013-08-131-14/+2
| | | | | | | | | | | | | | | | | | | | | | Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.

| | | | | | | | | | | Stop abusing xpt_periph in random plases that really have no periph related to CCB, for example, bus scanning. NULL value is fine in such cases and it is correctly logged in debug messages as "noperiph".

* MFC r252471:Steven Hartland2013-07-031-5/+8
| | | | | | | | | | | | | | | | | | Remove forced timeout of in-flight commands from mfi_timeout. While this prevents commands getting stuck forever there is no way to guarantee that data from the command hasn't been committed to the device. In addition older mfi firmware has a bug that would cause the controller to frequently stall IO for over our timeout value, which when combined with a forced timeout often resulted in panics in UFS; which would otherwise be avoided when the command eventually completed if left alone. For reference this timeout issue is resolved in Dell FW package 21.2.1-0000. Fixed FW package version for none Dell controller will likely vary. Notes: svn path=/stable/9/; revision=252554

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | have been in production at Netflix for several months with significant success. MFC r246713: Reform the busdma API so that new types may be added without modifying every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. MFC r249538: Some compilers issue a warning when wider integer is casted to narrow pointer. Supposedly shut down the warning by casting through uintptr_t. MFC r251479: Simplify the checking of flags for cam_periph_mapmem(). This gets rid of a lot of code redundancy and grossness at very minor expense. MFC r251837: MFC r251842: Add infrastructure for doing compatibility shims, as has been sorely needed for the last 10 years. Far too much of the internal API is exposed, and every small adjustment causes applications to stop working. To kick this off, bump the API version to 0x17 as should have been done with r246713, but add shims to compensate. Thanks to the shims, there should be no visible change in application behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | - Extend the prior commit to use the generic SCSI command building function use that for JBOD and Thunderbolt disk write command. Now we only have one implementation in mfi. - Fix dumping on Thunderbolt cards. Polled IO commands do not seem to be normally acknowledged by changing cmd_status to MFI_STAT_OK. In order to get acknowledgement of the IO is complete, the Thunderbolt command queue needs to be run through. I added a flag MFI_CMD_SCSI to indicate this command is being polled and to complete the Thunderbolt wrapper and indicate the result. This flag needs to be set in the JBOD case in case if that us using Thunderbolt card. When in the polling loop check for completed commands. - Remove mfi_tbolt_is_ldio and just do the check when needed. - Fix an issue when attaching of disk device happens when a device is already scheduled to be attached but hasn't attached. - add a tunable to allow raw disk attachment to CAM via: hw.mfi.allow_cam_disk_passthrough=1 - fixup aborting of commands (AEN and LD state change). Use a generic abort function and only wait the command being aborted not both. Thunderbolt cards don't seem to abort commands so the abort times out. Notes: svn path=/stable/9/; revision=243824

| | | | | | | | | | | | | | | | | | | | | Fix panics triggered by older mfiutil binaries run on the new mfi(4) driver. The new driver changed the size of the mfi_dcmd_frame structure in such a way that a MFI_IOC_PASSTHRU ioctl from an old amd64 binary is treated as an MFI_IOC_PASSTHRU32 ioctl in the new driver. As a result, the user pointer is treated as the buffer length. mfi_user_command() doesn't have a bounds check on the buffer length, so it passes a really big value to malloc() which panics when it tries to exhaust the kmem_map. Fix this two ways: - Only honor MFI_IOC_PASSTHRU32 if the binary has the SV_ILP32 flag set, otherwise treat it as an unknown ioctl. - Add a bounds check on the buffer length passed by the user. For now it fails any user attempts to use a buffer larger than 1MB. While here, fix a few other nits: - Remove an unnecessary check for a NULL return from malloc(M_WAITOK). - Use the ENOTTY errno for invalid ioctl commands instead of ENOENT.

* Second-to-last commit implementing Capsicum capabilities in the FreeBSDRobert Watson2011-08-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kernel for FreeBSD 9.0: Add a new capability mask argument to fget(9) and friends, allowing system call code to declare what capabilities are required when an integer file descriptor is converted into an in-kernel struct file *. With options CAPABILITIES compiled into the kernel, this enforces capability protection; without, this change is effectively a no-op. Some cases require special handling, such as mmap(2), which must preserve information about the maximum rights at the time of mapping in the memory map so that they can later be enforced in mprotect(2) -- this is done by narrowing the rights in the existing max_protection field used for similar purposes with file permissions. In namei(9), we assert that the code is not reached from within capability mode, as we're not yet ready to enforce namespace capabilities there. This will follow in a later commit. Update two capability names: CAP_EVENT and CAP_KEVENT become CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they represent.
