orinoco: Move context allocation after processing the skb

2020-12-29T12:42:37Z

[ Upstream commit a31eb615646a63370aa1da1053c45439c7653d83 ] ezusb_xmit() allocates a context which is leaked if orinoco_process_xmit_skb() returns an error. Move ezusb_alloc_ctx() after the invocation of orinoco_process_xmit_skb() because the context is not needed so early. ezusb_access_ltv() will cleanup the context in case of an error.

orinoco: avoid assertion in case of NULL pointer

2020-02-28T14:38:59Z

[ Upstream commit c705f9fc6a1736dcf6ec01f8206707c108dca824 ] In ezusb_init, if upriv is NULL, the code crashes. However, the caller in ezusb_probe can handle the error and print the failure message. The patch replaces the BUG_ON call to error return. Signed-off-by: Aditya Pakki Signed-off-by: Kalle Valo Signed-off-by: Sasha Levin

orinoco_usb: fix interface sanity check

2020-02-05T13:03:30Z

commit b73e05aa543cf8db4f4927e36952360d71291d41 upstream. Make sure to use the current alternate setting when verifying the interface descriptors to avoid binding to an invalid interface. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

orinoco_usb: return error in ezusb_probe when alloc_orinocodev fails

2015-10-28T18:55:47Z

The current code exits after alloc_orinocodev, but fails to change the return value to something that indicates the failure. This patch changes the return value to -ENOMEM. https://bugzilla.kernel.org/show_bug.cgi?id=106181 Signed-off-by: John W. Linville Signed-off-by: Kalle Valo

orinoco: fix checking for default value

2015-09-22T23:14:32Z

Thresholds uses -1 to indicate that default value should be used. Since thresholds are unsigned sign checking makes no sense. The problem has been detected using proposed semantic patch scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1].

orinoco: Do not call wiphy_unregister() from free_orinocodev()

2015-08-13T12:36:47Z

alloc_orinocodev() would allocate the wiphy entry, but it would only get registered much later in orinoco_init(). If something failed in the init process inbetween the call to alloc_orinocodev() and the completion of orinoco_init(), the drivers would end up calling wiphy_unregister() with a NULL pointer causing beautiful OOPS fireworks. Explicitly call wiphy_unregister() instead in the right places. Signed-off-by: Jes Sorensen Signed-off-by: Kalle Valo

cfg80211-wext: export symbols only when needed

2015-02-28T20:31:09Z

When a fully converted cfg80211 driver needs cfg80211-wext for userspace API purposes, the symbols need not be exported. When other drivers (orinoco/hermes or ipw2200) are enabled, they do need the symbols exported as they use them directly. Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig symbol (instead of just CFG80211_WEXT) and export the functions only if requested - this saves about 1/2k due to the size of EXPORT_SYMBOL() itself.
