staging: rtl8723bs: simplify control flow Checkpatch issues "WARNING: else is not generally useful after a break or return" for the following code: while (1) { do_join_r = rtw_do_join(padapter); if (do_join_r == _SUCCESS) { break; } else { rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) > 0) { continue; } else { rtw_indicate_disconnect(padapter); break; } } } We simplify this code in multiple steps. First, we remove do_join_r variable because it is only used right after it is assigned. Second, we remove the unnecessary else statement right after break: while (1) { if (rtw_do_join(padapter) == _SUCCESS) break; rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) > 0) { continue; } else { rtw_indicate_disconnect(padapter); break; } } Next, we move the call to rtw_do_join into the while test because the while will loop only until the call is successful: while (rtw_do_join(padapter) != _SUCCESS) { rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) > 0) { continue; } else { rtw_indicate_disconnect(padapter); break; } } Finally, looking at the code above, it is clear that the code will break out of the loop if rtw_to_roam call is <= 0. Hence: while (rtw_do_join(padapter) != _SUCCESS) { rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) <= 0) { rtw_indicate_disconnect(padapter); break; } } Signed-off-by: Sevinj Aghayeva <sevinj.aghayeva@gmail.com> Link: https://lore.kernel.org/r/20220403224207.GA397480@euclid Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This requires changing rtw_free_all_stainfo() so that it does its freeing in 2 steps, first moving all stainfo-s to free to a local list while holding the sta_hash_lock and then walking that list to call rtw_free_stainfo() on them without holding the sta_hash_lock. Pushing the taking of sta_hash_lock down into rtw_free_stainfo(), also fixes a whole bunch of callers of rtw_free_stainfo() which were not holding that lock even though they should. Note that this also fixes the deadlock from the "remove possible deadlock when disconnect" patch in a different way. But the changes from that patch offer a nice locking cleanup regardless.

staging: rtl8723bs: replace DBG_871X_LEVEL logs with netdev_*() Replace DBG_871X_LEVEL logs with netdev_*() functions where possible (i.e. where a pointer to netdev is easily available). This is not possible in correspondance of redundant log in module initialization. So remove those ones. DBG_871X_LEVEL macro wraps a raw printk call which is not recommended in a device driver context, prefer using netdev_*() log functions. The remove/replace operation has been done with the following semantic patch script: @@ expression list args; identifier padapter; identifier func; symbol _drv_always_, _drv_info_, _drv_warning_; symbol _drv_err_, _drv_emerg_; @@ func(..., struct adapter *padapter, ...) { <...

This patch replaces cases of: vzalloc(a * b) with: vzalloc(array_size(a, b)) as well as handling cases of: vzalloc(a * b * c) with: vzalloc(array3_size(a, b, c)) This does, however, attempt to ignore constant size factors like: vzalloc(4 * 1024) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( vzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | vzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT; typedef u8; typedef __u8; @@ ( vzalloc( - sizeof(u8) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(__u8) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(char) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(unsigned char) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(u8) * COUNT + COUNT , ...) | vzalloc( - sizeof(__u8) * COUNT + COUNT , ...) | vzalloc( - sizeof(char) * COUNT + COUNT , ...) | vzalloc( - sizeof(unsigned char) * COUNT + COUNT , ...) ) // 2-factor product with sizeof(type/expression) and identifier or constant. @@ type TYPE; expression THING; identifier COUNT_ID; constant COUNT_CONST; @@ ( vzalloc( - sizeof(TYPE) * (COUNT_ID) + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT_ID + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT_CONST + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vzalloc( - sizeof(THING) * (COUNT_ID) + array_size(COUNT_ID, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT_ID + array_size(COUNT_ID, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT_CONST + array_size(COUNT_CONST, sizeof(THING)) , ...) ) // 2-factor product, only identifiers. @@ identifier SIZE, COUNT; @@ vzalloc( - SIZE * COUNT + array_size(COUNT, SIZE) , ...) // 3-factor product with 1 sizeof(type) or sizeof(expression), with // redundant parens removed. @@ expression THING; identifier STRIDE, COUNT; type TYPE; @@ ( vzalloc( - sizeof(TYPE) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(THING) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) ) // 3-factor product with 2 sizeof(variable), with redundant parens removed. @@ expression THING1, THING2; identifier COUNT; type TYPE1, TYPE2; @@ ( vzalloc( - sizeof(TYPE1) * sizeof(TYPE2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vzalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vzalloc( - sizeof(THING1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vzalloc( - sizeof(THING1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vzalloc( - sizeof(TYPE1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) | vzalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) ) // 3-factor product, only identifiers, with redundant parens removed. @@ identifier STRIDE, SIZE, COUNT; @@ ( vzalloc( - (COUNT) * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - (COUNT) * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - (COUNT) * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - (COUNT) * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) ) // Any remaining multi-factor products, first at least 3-factor products // when they're not all constants... @@ expression E1, E2, E3; constant C1, C2, C3; @@ ( vzalloc(C1 * C2 * C3, ...) | vzalloc( - E1 * E2 * E3 + array3_size(E1, E2, E3) , ...) ) // And then all remaining 2 factors products when they're not all constants. @@ expression E1, E2; constant C1, C2; @@ ( vzalloc(C1 * C2, ...) | vzalloc( - E1 * E2 + array_size(E1, E2) , ...) ) Signed-off-by: Kees Cook <keescook@chromium.org>

staging: rtl8723bs: avoid null pointer dereference on pmlmepriv 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.

staging: Add rtl8723bs sdio wifi driver The rtl8723bs is found on quite a few systems used by Linux users, such as on Atom systems (Intel Computestick and various other Atom based devices) and on many (budget) ARM boards such as the CHIP. The plan moving forward with this is for the new clean, written from scratch, rtl8xxxu driver to eventually gain support for sdio devices. But there is no clear timeline for that, so lets add this driver included in staging for now.
