2021-08-30console: consume APC, DM, DCSnick black
The Linux console's VT102 implementation already consumes OSC ("Operating System Command") sequences, probably because that's how palette changes are transmitted. In addition to OSC, there are three other major clases of ANSI control strings: APC ("Application Program Command"), PM ("Privacy Message"), and DCS ("Device Control String"). They are handled similarly to OSC in terms of termination. Source: vt100.net Add three new enumerated states, one for each of these types. All three are handled the same way right now--they simply consume input until terminated. I hope to expand upon this firmament in the future. Add new predicate ansi_control_string(), returning true for any of these states. Replace explicit checks against ESosc with calls to this function. Transition to these states appropriately from the escape initiation (ESesc) state. This was motivated by the following Notcurses bugs: https://github.com/dankamongmen/notcurses/issues/2050 https://github.com/dankamongmen/notcurses/issues/1828 https://github.com/dankamongmen/notcurses/issues/2069 where standard VT sequences are not consumed by the Linux console. It's not necessary that the Linux console *support* these sequences, but it ought *consume* these well-specified classes of sequences. Tested by sending a variety of escape sequences to the console, and verifying that they still worked, or were now properly consumed. Verified that the escapes were properly terminated at a generic level. Verified that the Notcurses tools continued to show expected output on the Linux console, except now without escape bleedthrough.

2021-08-30xen/blkfront: don't trust the backend response data blindlyJuergen Gross
Today blkfront will trust the backend to send only sane response data. In order to avoid privilege escalations or crashes in case of malicious backends verify the data to be within expected limits. Especially make sure that the response always references an outstanding request. Introduce a new state of the ring BLKIF_STATE_ERROR which will be switched to in case an inconsistency is being detected. Recovering from this state is possible only via removing and adding the virtual device again (e.g. via a suspend/resume cycle). Make all warning messages issued due to valid error responses rate limited in order to avoid message floods being triggered by a malicious backend.

The driver is being passed interrupts, then looking up the same interrupts as GPIOs a second time to convert them into interrupts and set properties on them. This is pointless: the GPIO and irqchip APIs of a GPIO chip are orthogonal. Just request the interrupts and be done with it, drop reliance on any GPIO functions or definitions. Use devres-managed functions and add a small devress quirk to unregister the clock as well and we can rely on devres to handle all the resources and cut down a bunch of boilerplate in the process.

2021-08-30ixp4xx_eth: make ptp support a platform driverArnd Bergmann
After the recent ixp4xx cleanups, the ptp driver has gained a build failure in some configurations: drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init': drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function) Avoid the last bit of hardcoded constants from platform headers by turning the ptp driver bit into a platform driver and passing the IRQ and MMIO address as resources. This is a bit tricky: - The interface between the two drivers is now the new ixp46x_ptp_find() function, replacing the global ixp46x_phc_index variable. The call is done as late as possible, in hwtstamp_set(), to ensure that the ptp device is fully probed. - As the ptp driver is now called by the network driver, the link dependency is reversed, which in turn requires a small Makefile hack - The GPIO number is still left hardcoded. This is clearly not great, but it can be addressed later. Note that commit 98ac0cc270b7 ("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the IRQ number to something meaningless. Passing the correct IRQ in a resource fixes this. - When the PTP driver is disabled, ethtool .get_ts_info() now correctly lists only software timestamping regardless of the hardware.

2021-08-30bnxt_en: support multiple HWRM commands in flightEdwin Peer
Add infrastructure to maintain a pending list of HWRM commands awaiting completion and reduce the scope of the hwrm_cmd_lock mutex so that it protects only the request mailbox. The mailbox is free to use for one or more concurrent commands after receiving deferred response events. For uniformity and completeness, use the same pending list for collecting completions for commands that respond via a completion ring. These commands are only used for freeing rings and for IRQ test and we only support one such command in flight. Note deferred responses are also only supported on the main channel. The secondary channel (KONG) does not support deferred responses. Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2021-08-30bnxt_en: update all firmware calls to use the new APIsEdwin Peer
The conversion follows this general pattern for most of the calls: 1. The input message is changed from a stack variable initialized using bnxt_hwrm_cmd_hdr_init() to a pointer allocated and intialized using hwrm_req_init(). 2. If we don't need to read the firmware response, the hwrm_send_message() call is replaced with hwrm_req_send(). 3. If we need to read the firmware response, the mutex lock is replaced by hwrm_req_hold() to hold the response. When the response is read, the mutex unlock is replaced by hwrm_req_drop(). If additional DMA buffers are needed for firmware response data, the hwrm_req_dma_slice() is used instead of calling dma_alloc_coherent(). Some minor refactoring is also done while doing these conversions. v2: Fix unintialized variable warnings in __bnxt_hwrm_get_tx_rings() and bnxt_approve_mac() Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2021-08-30bnxt_en: use link_lock instead of hwrm_cmd_lock to protect link_infoEdwin Peer
We currently use the hwrm_cmd_lock to serialize the update of the firmware's link status response data and the copying of link status data to the VF. This won't work when we update the firmware message APIs, so we use the link_lock mutex instead. All link_info data should be updated under the link_lock mutex. Also add link_lock to functions that touch link_info in __bnxt_open_nic() and bnxt_probe_phy(). The locking is probably not strictly necessary during probe, but it's more consistent.

2021-08-30bnxt_en: add support for HWRM request slicesEdwin Peer
Slices are a mechanism for suballocating DMA mapped regions from the request buffer. Such regions can be used for indirect command data instead of creating new mappings with dma_alloc_coherent(). The advantage of using a slice is that the lifetime of the slice is bound to the request and will be automatically unmapped when the request is consumed. A single external region is also supported. This allows for regions that will not fit inside the spare request buffer space such that the same API can be used consistently even for larger mappings.

2021-08-30bnxt_en: introduce new firmware message API based on DMA poolsEdwin Peer
This change constitutes a major step towards supporting multiple firmware commands in flight by maintaining a separate response buffer for the duration of each request. These firmware commands are also known as Hardware Resource Manager (HWRM) commands. Using separate response buffers requires an API change in order for callers to be able to free the buffer when done. It is impossible to keep the existing APIs unchanged. The existing usage for a simple HWRM message request such as the following: struct input req = {0}; bnxt_hwrm_cmd_hdr_init(bp, &req, REQ_TYPE, -1, -1); rc = hwrm_send_message(bp, &req, sizeof(req), HWRM_CMD_TIMEOUT); if (rc) /* error */ changes to: struct input *req; rc = hwrm_req_init(bp, req, REQ_TYPE); if (rc) /* error */ rc = hwrm_req_send(bp, req); /* consumes req */ if (rc) /* error */ The key changes are: 1. The req is no longer allocated on the stack. 2. The caller must call hwrm_req_init() to allocate a req buffer and check for a valid buffer. 3. The req buffer is automatically released when hwrm_req_send() returns. 4. If the caller wants to check the firmware response, the caller must call hwrm_req_hold() to take ownership of the response buffer and release it afterwards using hwrm_req_drop(). The caller is no longer required to explicitly hold the hwrm_cmd_lock mutex to read the response. 5. Because the firmware commands and responses all have different sizes, some safeguards are added to the code. This patch maintains legacy API compatibiltiy, implementing the old API in terms of the new. The follow-on patches will convert all callers to use the new APIs. v2: Fix redefined writeq with parisc .config Fix "cast from pointer to integer of different size" warning in hwrm_calc_sentinel() Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2021-08-30bnxt_en: remove DMA mapping for KONG responseEdwin Peer
The additional response buffer serves no useful purpose.

It is thus safe to share a single DMA buffer. Removing the code associated with the additional mapping will simplify matters in the next patch, which allocates response buffers from DMA pools on a per request basis.
