To: Greg Kroah-Hartman; +Cc: linux-staging, linux-kernel, Rishik Yechuri
The driver defines GetAddr1Ptr() through GetAddr4Ptr() in wifi.h to
obtain pointers to the address fields of an IEEE 802.11 header by
adding hardcoded byte offsets to the frame buffer. This duplicates
struct ieee80211_hdr from <linux/ieee80211.h>, which describes the
same layout and is used throughout the wireless subsystem.
Replace each use of these macros with the corresponding addr1..addr4
member of struct ieee80211_hdr, and remove the macro definitions.
Several functions in rtw_mlme_ext.c already access the header through
struct ieee80211_hdr. This makes the remaining call sites consistent
with them.
Include <linux/ieee80211.h> directly in wifi.h, since the inline helpers
there now depend on struct ieee80211_hdr.
This is the first step towards replacing the driver's private 802.11
header macros with the generic helpers provided by the kernel.
No functional change intended.

From: Rishik Yechuri @ 2026-10-13 20:15 UTC (permalink / raw)
To: Greg Kroah-Hartman; +Cc: linux-staging, linux-kernel, Rishik Yechuri
The driver defines GetToDs(), GetFrDs(), get_tofr_ds(), GetMFrag(),
GetRetry(), GetPwrMgt(), GetMData(), GetPrivacy() and GetOrder() in
wifi.h to test individual bits of the IEEE 802.11 Frame Control field.
Each macro casts the frame buffer to __le16 and masks a single bit.
<linux/ieee80211.h> provides equivalent helpers that operate on the
frame_control member of struct ieee80211_hdr and test the same bits.
Replace each use of these macros with the corresponding helper:
GetToDs() -> ieee80211_has_tods()
GetFrDs() -> ieee80211_has_fromds()
GetMFrag() -> ieee80211_has_morefrags()
GetRetry() -> ieee80211_has_retry()
GetPwrMgt() -> ieee80211_has_pm()
GetMData() -> ieee80211_has_moredata()
GetPrivacy() -> ieee80211_has_protected()
GetOrder() -> ieee80211_has_order()
Open code get_tofr_ds() using ieee80211_has_tods() and
ieee80211_has_fromds(), and remove the macro definitions. Also remove
GetOrderBit(), which has no users.
No functional change intended.

The driver defines SetToDs(), SetFrDs(), SetMFrag(), ClearMFrag(),
ClearRetry(), SetPwrMgt(), ClearPwrMgt(), SetMData(), ClearMData() and
SetPrivacy() in wifi.h to set and clear bits of the IEEE 802.11 Frame
Control field, using private _TO_DS_ through _ORDER_ bit definitions
that duplicate the IEEE80211_FCTL_* constants in <linux/ieee80211.h>.
Replace each use of these macros by operating on the frame_control
member directly with the corresponding IEEE80211_FCTL_* mask, as is
done elsewhere in the wireless subsystem.
In rtw_xmitframe_coalesce(), the header pointer is updated on each
iteration of the fragmentation loop, since mem_start advances to a new
fragment each time.
When constructing the BIP additional authentication data, mask the
Retry, Power Management and More Data bits in a local copy of the
Frame Control field before copying it into the buffer. This matches
bip_aad() in net/mac80211/wpa.c.
Remove the macro definitions and the private bit definitions, which no
longer have any users. Also remove the mem_start variable from
rtw_mgmt_xmitframe_coalesce(), as its only use was the SetPrivacy()
call.
No functional change intended.

To: Greg Kroah-Hartman; +Cc: linux-staging, linux-kernel, Rishik Yechuri
Several functions test whether a received or transmitted frame is of
one particular type or subtype by comparing the result of
GetFrameType() or GetFrameSubType() against the driver's WIFI_*
constants. <linux/ieee80211.h> provides ieee80211_is_*() helpers that
perform the same tests on the frame_control member of
struct ieee80211_hdr.
Replace these single comparisons with the corresponding helpers:
GetFrameType() == WIFI_MGT_TYPE -> ieee80211_is_mgmt()
GetFrameType() == WIFI_CTRL_TYPE -> ieee80211_is_ctl()
GetFrameType() == WIFI_DATA_TYPE -> ieee80211_is_data()
GetFrameSubType() == WIFI_BEACON -> ieee80211_is_beacon()
GetFrameSubType() == WIFI_PSPOLL -> ieee80211_is_pspoll()
GetFrameSubType() == WIFI_ASSOCREQ -> ieee80211_is_assoc_req()
GetFrameSubType() == WIFI_DEAUTH -> ieee80211_is_deauth()
GetFrameSubType() == WIFI_DISASSOC -> ieee80211_is_disassoc()
The QoS data test in sta2ap_data_frame() is replaced with
ieee80211_is_data_qos(). The helper additionally checks that the frame
type is data, which is always the case on this path since the frame
has already been classified as a data frame by validate_recv_frame().
Remove IsFrameTypeCtrl(), whose only caller is converted by this
change.
The remaining users of GetFrameType() and GetFrameSubType() are
converted separately.
No functional change intended.

To: Greg Kroah-Hartman; +Cc: linux-staging, linux-kernel, Rishik Yechuri
The remaining users of GetFrameType() and GetFrameSubType() switch on
the frame type or subtype, store it for several later comparisons, or
derive values from its individual bits. Convert them to operate on the
frame_control member of struct ieee80211_hdr.
Switch statements now mask frame_control with IEEE80211_FCTL_FTYPE or
IEEE80211_FCTL_STYPE and use cpu_to_le16(IEEE80211_FTYPE_*) or
cpu_to_le16(IEEE80211_STYPE_*) case labels, as is done in mac80211.
Where the subtype was stored in a local variable and compared against
several values, store the frame_control value instead and use the
ieee80211_is_*() helpers.
The test for the absence of a data payload in ap2sta_data_frame() and
sta2ap_data_frame() is replaced with ieee80211_is_data_present(), and
the QoS test in validate_recv_frame() with ieee80211_is_data_qos().
Both helpers additionally check that the frame type is data, which is
always the case on these paths.
In aes_cipher(), aes_decipher() and rtw_check_bcn_info(), the type and
subtype are kept as integer values and are now derived using the
IEEE80211_FCTL_* masks and compared against IEEE80211_FTYPE_* and
IEEE80211_STYPE_* values, which are numerically identical to the WIFI_*
values they replace.
Remove the GetFrameType() and GetFrameSubType() macros, which no longer
have any users.
No functional change intended.

The num member of struct mlme_handler is initialised in mlme_sta_tbl[]
with the WIFI_* subtype constants but is never read. The table is
indexed directly by the frame subtype in mgt_dispatcher(), and only the
func member of each entry is used.
Remove the member and its initialisers. This drops the last references
to several WIFI_* constants that have no equivalent in
<linux/ieee80211.h>, such as WIFI_ACTION_NOACK, so that the private
frame type definitions can be removed in a later change.
No functional change intended.

The driver sets the type and subtype of transmitted frames with
SetFrameSubType() using its private WIFI_* enumeration, which encodes
the same values as the IEEE80211_FTYPE_* and IEEE80211_STYPE_*
constants in <linux/ieee80211.h>.
Replace each SetFrameSubType() call with an OR of the corresponding
IEEE80211_FTYPE_* and IEEE80211_STYPE_* values into frame_control. At
every call site the Frame Control field has already been cleared, so
the type and subtype bits are zero and the OR is equivalent to the
clear and set performed by the macro. Flags that some callers set
before the subtype, such as Power Management and From DS, are
preserved as before.
Convert the values stored in pattrib->subtype and passed to
issue_asocrsp() to the kernel definitions as well. They are
numerically identical to the WIFI_* values they replace.
Remove SetFrameSubType(), the unused SetFrameType(), and the WIFI_*
frame type and subtype enumerations, which no longer have any users.
Update comments that referred to the removed constants.
No functional change intended.

From: Rishik Yechuri @ 2026-10-13 20:15 UTC (permalink / raw)
To: Greg Kroah-Hartman; +Cc: linux-staging, linux-kernel, Rishik Yechuri
The driver reads and writes the Sequence Control and Duration/ID fields
of IEEE 802.11 headers with the SetSeqNum(), GetSequence(),
GetFragNum(), SetDuration() and GetAid() macros, which access the
frame buffer at hardcoded byte offsets. struct ieee80211_hdr provides
the seq_ctrl and duration_id members for these fields, and
<linux/ieee80211.h> provides IEEE80211_SCTL_* masks and helpers to
convert between sequence numbers and the Sequence Control field.
Replace GetSequence() with ieee80211_get_sn(), GetFragNum() with a
mask of seq_ctrl with IEEE80211_SCTL_FRAG, and SetDuration() and
GetAid() with accesses to duration_id.
SetSeqNum() updates the sequence number while preserving the fragment
number. Where the header has just been cleared, replace it with an
assignment of IEEE80211_SN_TO_SEQ() to seq_ctrl. The reserved page
frames built in rtl8723b_cmd.c are written into a buffer that is not
cleared between uses. Those callers set a sequence number of zero, so
replace them with a mask that clears the sequence number and keeps the
fragment number, as SetSeqNum() did.
Remove these macros and the unused SetFragNum().
No functional change intended.

9 siblings, 0 replies; 11+ messages in thread
From: Rishik Yechuri @ 2026-10-13 20:15 UTC (permalink / raw)
To: Greg Kroah-Hartman; +Cc: linux-staging, linux-kernel, Rishik Yechuri
The driver reads and writes the QoS Control field with the
SetPriority(), GetPriority(), SetEOSP(), SetAckpolicy(),
GetAckpolicy() and GetAMsdu() macros, which shift and mask the field
by hand. <linux/ieee80211.h> defines IEEE80211_QOS_CTL_* masks for the
TID, EOSP, Ack Policy and A-MSDU Present subfields.
On transmit, set the subfields with le16_encode_bits() and the
corresponding masks, and declare the QoS Control pointers as __le16
to match the byte order of the field. le16_encode_bits() masks the
value to the width of the subfield, as the macros did.
On receive, locate the field with ieee80211_get_qos_ctl() instead of
a fixed offset of 24 bytes, and extract the subfields with
u8_get_bits(). Frames with four addresses are rejected by
validate_recv_data_frame() before the QoS Control field is parsed, so
the helper always returns the same offset as before.
Remove the macro definitions, which no longer have any users.
No functional change intended.

To: Greg Kroah-Hartman; +Cc: linux-staging, linux-kernel, Rishik Yechuri
get_da() and get_sa() in wifi.h select the destination and source
address of a frame according to the To DS and From DS bits. They
duplicate ieee80211_get_DA() and ieee80211_get_SA() from
<linux/ieee80211.h>, which return the same address for every
combination of these bits.
rtl8723bs_get_ra() and get_ta() only return the addr1 and addr2
members of the header.
Replace get_da() and get_sa() with the generic helpers, replace
rtl8723bs_get_ra() and get_ta() with direct accesses to addr1 and
addr2, and remove the four functions.
No functional change intended.
