update the values if they are non-zero and smaller than the current hardcoded depths. Fixes dwiic(4) on Ampere eMAG. ok patrick@, jcs@
2019-08-05Favor vn_close() in the error path of diskmapioctl() since side-effectsanton
caused by calling vn_open() with write permissions must be reverted. Otherwise, the vfs subsystem could panic while releasing the last vnode reference if the writecount is still positive. ok visa@ Reported-by: syzbot+4724df09d9ab0fdca28a@syzkaller.appspotmail.com Reported-by: syzbot+a430606fd528645559db@syzkaller.appspotmail.com
2019-08-05Allow concurrent reads of the f_offset field of struct file byanton
serializing both read/write operations using the existing file mutex. The vnode lock still grants exclusive write access to the offset; the mutex is only used to make the actual write atomic and prevent any concurrent reader from observing intermediate values. ok mpi@ visa@

2019-07-31ihidev: continue doing polling when interrupt setup failsJoshua Stein
2019-07-31dwiic_acpi: handle GPIO interrupts when we have no appropriate driverJoshua Stein
Avoid printing a confusing "irq 0" message in this case.
2019-07-31dwiic: stop enabling polling by defaultJoshua Stein
The interrupt problem had nothing to do with changes in the Intel 100 Series and was due to most of these machines using the same DSDT template where we were walking _INI nodes in the wrong order. This lead to the touchpad device's _INI method being called before \_SB_.PCI0._INI (where \OSYS is initialized), making the touchpad device's interrupts setup for an OSYS of 0, but when its _CRS method was called later during ihidev attachment (after \_SB_.PCI0._INI was executed, modifying OSYS), it returned information for interrupts as if were initially setup for the proper OSYS.
2019-07-31aml_find_node: perform callback on matched direct-child nodes beforeJoshua Stein
recursing into child devices looking for matches. This ensures that when walking nodes with acpi_inidev, a method like \_SB_.PCI0._INI will be executed before \_SB_.PCI0.I2C1.TPL1._INI. This matches how ACPICA walks nodes and a commonly-used DSDT template assumes that \OSYS has been initialized in \_SB_.PCI0._INI before being used by other device _INI methods. This should also help to execute \_INI and \_SB_._INI first, if present, which ACPICA does explicitly. Tested in snaps, ok deraadt

2019-07-30push rxed packets to the stack once per interrupt (per port)David Gwynne
pushing to the stack on every packet completion interacts badly with the backpressure mechanism in ifiq_input when you rx more than 8 or so packets per interrupt. while here move to ifiq_input and apply backpressure before we start dropping in software. the problem was found by olivier taibi and reported on bugs@ i tested this on an overdrive 1000 which uses msk for its onboard nic

2019-07-29Add support for 802.11n Tx aggregation to net80211 and the iwn(4) driver.Stefan Sperling
In particular, add Tx block ack session management to net80211, with enough funcionality to support Tx aggregation on devices which perform A-MPDU subframe scheduling in firmware. Make use of the iwn(4) firmware Tx scheduler to build A-MPDUs. net80211's QoS support code is now enabled and used by Tx aggregation. A-MSDU frames inside A-MPDUs have been tested and work in principle. For now, this feature is disabled because unfair TCP connection sharing was observed during testing, where bursts of TCP Ack frames for a single tcpbench(1) connection arriving in A-MSDUs made other TCP connections stall. Switch off support for A-MSDUs inside A-MPDUs on the Rx side as well. Tested on iwn chipsets 1000, 4965, 5100, 5300, 2200, 6200, 6205, 6300 (committed version of tested diff has all debug printfs removed) tests/ok benno kmos mlarkin kevlo
