    …y-one mistake in core/rtw_mlme_ext.c"

    commit 87e4a5405f087427fbf8b437d2796283dce2b38f upstream.

    pstapriv->max_num_sta is always <= NUM_STA, since max_num_sta is either
    set in _rtw_init_sta_priv() or rtw_set_beacon().

    commit 8561fb31a1f9594e2807681f5c0721894e367f19 upstream.

    With Androidx86 8.1, wificond returns "failed to get
    nl80211_sta_info_tx_failed" and wificondControl returns "Invalid signal
    poll result from wificond". The fix is to OR sinfo->filled with
    BIT_ULL(NL80211_STA_INFO_TX_FAILED).

    This missing bit is apparently not needed with NetworkManager, but it
    does no harm in that case.

    commit 920c92448839bd4f8eb87a92b08cad56d449caff upstream.

    Dan Carpenter reported an integer underflow issue in the rtl8188eu driver.
    This is also needed for the length (signed integer) in rtl8723bs, as it is
    later converted to an unsigned integer and used in a memcpy operation.

    Original issue is at https://patchwork.kernel.org/patch/9796371/

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • ec1412193   staging: rtl8723bs: avoid null pointer dereference on pmlmepriv ... Browse Code »

    There is a check to see if pmlmepriv is null before vfree'ing
    pmlmepriv->free_bss_buf hence implying pmlmepriv could potenially be
    null. However, a previous call to rtw_free_mlme_priv_ie_data
    can also dereference pmlmepriv, so move this call so that it is only
    called if pmlmepriv non-null.
