| <li>Added or improved wireless network drivers: | <li>Added or improved wireless network drivers: | ||
| <ul> | <ul> | ||
| <li>... | <li>Zeroed out <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> Tx descriptors of frames which are done to prevent the device from writing to the former DMA address of a buffer which has been taken off the Tx ring. | ||
| <li>Fixed a bug in <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> Tx done interrupt processing which could cause fatal firmware errors under load and memory corruption. | |||
| <li>Changed <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> to sleep for 1 second while loading firmware to match what <a href="https://man.openbsd.org/iwn.4">iwn(4)</a> does. This fixes some issues with suspend/resume. | |||
| <li>Ensured that <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> will reload firmware from disk on down/up and not during resume. | |||
| <li>Fixed <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> crystal latency values to match those used by Linux iwlwifi. | |||
| <li>Fixed an off-by-one error in <a href="https://man.openbsd.org/bwfm.4">bwfm(4)</a>. | |||
| <li>Changed <a href="https://man.openbsd.org/iwn.4">iwn(4)</a>, <a href="https://man.openbsd.org/iwm.4">iwm(4)</a>, and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> devices to hide detailed firmware error reports by default. | |||
| <li>Prevented a loop when <a href="https://man.openbsd.org/bwfm.4">bwfm(4)</a> receives an unsolicited association status event right after successful association. | |||
| <li>Fixed <a href="https://man.openbsd.org/ure.4">ure(4)</a> after a media link change on RTL8153/B devices. | |||
| <li>Fixed a leak with <a href="https://man.openbsd.org/wg.4">wg(4)</a> keepalive. | |||
| <li>Switched <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> to -63 firmware images as shipped in iwx-firmware-20210512, including fixes addressing fragattacks vulnerabilities. | |||
| <li>Supported the new <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> firmware session protection command, required for successful associations with new firmware. | |||
| <li>Stopped asking <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> to send probe requests on passive channels, fixing firmware going unresponsive after association. | |||
| <li>Fixed an <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> edge case where devices failed to resume after system suspend. | |||
| <li>Switched <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> to newer firmware images available in iwm-firmware-20210512. This provides FragAttacks fixes for the updated devices. | |||
| <li>Fixed <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> against access points using TKIP as the group cipher. | |||
| <li>Prevented <a href="https://man.openbsd.org/athn.4">athn(4)</a> from calling ieee80211_find_rxnode() on bad frames in an attempt to prevent creation of bogus node cache entries. | |||
| <li>Implemented various fixes addressing firmware errors in <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a>. | |||
| <li>Fixed node leaks in <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> which caused the drivers to get stuck when roaming between access points. | |||
| <li>Fixed <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> firmware reloading after a failure to parse the firmware file. | |||
| <li>Avoided "mac clock not ready" panics in <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a>. | |||
| <li>Worked around a problem with certain <a href="https://man.openbsd.org/athn.4">athn(4)</a> hardware that caused problem when running in HostAP mode with clients that use Tx aggregation. | |||
| <li>Corrected multicast decryption for <a href="https://man.openbsd.org/iwx.4">iwx(4)</a>. | |||
| <li>Added 802.11n Tx aggregation support to <a href="https://man.openbsd.org/iwm.4">iwm(4)</a>. | |||
| <li>Made <a href="https://man.openbsd.org/iwn.4">iwn(4)</a>, <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> keep track of beacon parameters at run-time. | |||
| <li>Implemented support for Rx aggregation offload in <a href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> and re-enabled de-aggregation of A-MSDUs in net80211 for all drivers capable of 11n mode. | |||
| <li>Changed error reporting for <a href="https://man.openbsd.org/bwfm.4">bwfm(4)</a> to use the long version of the firmware path. This makes it easier to find the correct files to add to the bwfm-firmware port. | |||
